Agaves and a few of their kin - Cistus

1Agaves and a few of their kin

Agave aff. parryi [Mt. Emory, AZ]

Tightly clumping agave with seriously impressive leaves and extremely sharp spines. 3 ft tall and wide. Best in full

sun with excellent drainage. Allow to dry in winter. Classic playground plant. Cold hardy to 0F - USDA zone 7.

Agave americana

Deriving its common name from the alleged time it takes to flower (actually 2 decades is typical), this somewhat

less hardy agave is extremely handsome in a container. Meaty leaves with the previous leaf’s outline in relief. Full

sun. Frost hardy to 15F - mid USDA zone 8 with good drainage. Widespread in Mexico and possibly the US

southwest, though so long in cultivation that much of the original habitat is unknown.

Agave americana ‘Aureovariegata’

Classic large agave, in cultivation for so long its origins are not entirely known. Certainly central to northern

Mexico, this large, variegated form has leaves, eventually approaching 5 ft to 8 ft in the garden, with creamy

yellow margins and dusted blue-green centers. One plant in Brookings, OR, measures 11 x 11 ft as a single

rosette! In pots, they can be kept much smaller and are quick to exhibit the beautiful and classic, curved agave

shape. USDA zone 9 and, with protection such as dry areas under eaves or particularly dry climates, zone 8.

Agave americana 'Cornelius'

Miniature form of the monstrous Century Plant, forming rosettes to under 2 ft, each leaf centered green with

pleasing cream to gold leaf margins. In stunted form gives whole plant the appearance of a star. Frost hardy to

upper USDA zone 8 or a bit colder if dry and under an the eaves or another protected spot in winter. Either way a

fabulous pot plant. Full sun.

Agave americana - dwarf

The blue version of the oft sought after Agave americana ‘Mediopicta’. This picturesque plant grows to about 4 ft,

freely offsetting. Every so lightly more frost hardy than typical - to the low to mid teens - USDA zone 8, even

lower if dry. Some summer water with winter drought if possible. Otherwise typical century plant care.

Agave americana 'Mediopicta Alba'

Beautifully variegated diminutive form, the rosettes spreading to no more than 2-3 ft with beautifully curved

leaves, a dusty blue-green centered with wide creamy stripes. Slowly offsetting. As luck would have it one of the

forms hardier to frost with plants surviving 10 to 15F - USDA zone 8 - in winter dry soil. Pull in or cover below

20F or so in areas of winter wet.

Agave americana 'Opal'

A variegated agave from the larger group often just called Marginata’ or ‘Variegata,’ this one most pleasingly

variegated in creamy yellow on upright, blue-green foliage with sharp spines. To 4-5 ft tall and wide. Shared with

us by plantsman Tony Avent as having been hardy in coastal Virginia. Though it has been nuked in North Carolina

below 10F with winter moisture, it does show promise as being one of the tougher of the americana group as a very

similar plant has grown unharmed in Portland gardens for a number of years. We expect at least 15F, mid USDA

zone 8, and possibly lower if winter dry. In any zone a striking pot or container plant. Sun, well-drained soil, and

little summer water.

Agave americana ssp. protoamericana

A robust, stout, particularly silver-blue form from northeastern Mexico, the 6 ft or larger rosettes have proven a bit

more moisture and cold resilient than its cousins. Surviving temperatures of 10 to 15F with good drainage, it

reaches its greatest potential in large containers or in the open ground. Makes a fine focal point.

Agave americana - typical form

A plant so long in cultivation that it's wild origins are uncertain. Often seen in the US Southwest and along the

West Coast as well as in dry and Mediterranean climates worldwide. Open arching silver-blue rosettes to 6 ft or

more, eventually offsetting to form colonies. This fast growing century plant makes a fine and picturesque pot

specimen and can be kept smaller by being root bound. Provide excellent drainage and full sun. Hardy to 15ºF or

so.

Agave americana ‘Variegata’

Striking plant with beautiful curved, blue leaves edged in rich cream. Fine in pots or as an imposing garden icon

where winter temperatures seldom dive to below 20ºF - USDA zone 9 - for any length of time; has survived 8F

with dry, overhead protection. A plant in Brookings, OR measures 10 x 10 ft. after 10 years.

Agave attenuata 'Nova'

Striking blue form of this classic warm climate species from coastal southwest Mexico. Great indoor/outdoor

houseplant to about 2 ft, slowly forming a trunk with, eventually, a tall arching flower stalk. A lover of moisture

but, as with all agaves, requires good drainage. Can be planted outside where temperatures rarely fall below 28F -

upper USDA zone 9.

Agave 'Blue Glow'

Handsome, small agave, its stiff leaves, 1-1.5" wide, blue-green with red margins edged with yellow and a red

terminal spine -- particularly lovely when backlit. Plants are small, 1-2 ft tall and wide a maturity. This hybrid

between A. ocahui and A. attenuata, created by Kelly Griffin, is solitary, enjoying full sun, good drainage, and little

summer water. Frost hardy to at least 15F, mid USDA zone 8 --- always with good drainage -- and possibly lower.



Agave bovicornuta

From a few locations in Sonora’s western Sierra Madre Occidental this 3-4 ft, acid-green sculpture has most unique

fluted and tuped margins. Offsets only sparsely. Happy with dappled shade especially in hottest climates as long as

wet leaves do not collect in the rosette center. A beautiful container plant, frost hardy into the upper teens to low

20s F - upper USDA zone 8 to zone 9.

Agave bracteosa

Looking more like a bromeliad, this agave’s lax, spineless leaves are very choice. Polycarpic and rare in

cultivation, plants love the cool summer nights of the Northwest. Found clinging to the high rocky mountains

between Saltillo and Monterrey in NE Mexico growing with pines and, yes, even Douglas fir. Half sun. Frost hardy

to 10F - USDA zone 8, when dry in winter.

Agave bracteosa ‘Calamar’

Looking more like a bromeliad, an agave with lax, spineless leaves that are very choice and, in this form,

consistently blue-tinted with fewer offsets than the species. Polycarpic and rare in cultivation, plants love the cool

summer nights of the Northwest. Found clinging to the high rocky mountains between Saltillo and Monterrey in

NE Mexico growing with pines and, yes, even Douglas fir. This form was selected by Texas plantsman Pat

McNeal. Half sun. Frost hardy to 10F, USDA zone 8.

Agave ‘Burnt Burgundy’

Probable hybrid of A. victoriae-reginae and A. pelona, from Gregg Star, chosen it for its unusual smooth,

dark-margined leaves tinted burgundy. Small, to only a 1 ft to 18", and slowly clumping. Frost hardiness so far to a

little under 20F - just below USDA zone 9 - in our now Eucalyptus shaded agave patch, but a fine pot specimen in

colder climates. Full to part sun. Eucalyptus mulch optional.

Agave celsii

From the mountains of eastern and northeastern Mexico., handsome 2 ft rosettes of fleshy, celadon-green leaves.

This agave is particularly good in light shade or with slightly heavier soils than most. Quick to offset and form a

mound looking a little bit like maturing heads of cabbage -- at least to us. These plants represent collections from

Carl and Wade at Yucca Do, from over 5,000' in the northern part of its range. For us, it has been reliable into the

low 20sF and could go lower.

Agave celsii 'Multicolor'

Coming to us from Holland, land of specialty succulent collectors, this handsome plant is found in northeastern

Mexico, in the Sierra Madre Orientale where it inhabits fog-shrouded cliffs at over 5,000 ft. In this form, upright,

blue-gray leaves edge in cream form rosettes to 18" tall and wide, eventually offsetting to form archtiectural

clumps. A good garden plant where temperatures remain above 15 to 18F, mid USDA zone 8, in full sun to part

shade. Surprisingly shade tolerant if not too wet in the cool season. A wonderful container specimen anywhere.



Agave cerulata

From Baja California and highly variable, this collection having 18” to 2 ft rosettes of narrow, chalky blue leaves

margined with dark spines. Accustomed to either winter or summer rainfall but with excellent drainage and bright

light. Offsetting to form small colonies. In most climates best suited as pot plants or outside in a very well drained

situation and where temperatures seldom fall to 20F.

Agave dasylirioides

New and obscure little century plants from Oaxaca appear almost as sea urchins perched on their jagged limestone

habitat. Each plant to about 6” or so with narrow, quill-like leaves of dusty blue green. Flower spikes, reaching to 8

ft or higher on mature plants, signal the end of the rosette. Hardy only into the low 20sF - USDA zone 9 - but a

beautiful and manageable pot specimen.

Agave deserti var. simplex

Representing something probably between A. mckelveyana and the much more widespread A. deserti, this

colonizing form produces 18 in. (roughly), quickly offsetting rosettes of striking bluish white leaves tipped with

dark spines. This collection is from the Kofa Mountains of western Arizona and, considering its habitat, these

plants would clearly like very sharp drainage and bright conditions. A fine pot plant. Hardy to 10º to 15ºF.

Agave deserti var. simplex ‘Kofa Queen’ SBH6770A Cistus introduction. A beautiful species ranging from northern Baja to the southern Mojave and east central

Arizona and Sonora. This collection represents a northeastern habitat in Arizona's Kofa mountains where this

supposedly sparsely offsetting subspecies reigns. These mountains are also known for the endemic Mahonia

harrisoniana and as the furthest north, relictual colony of Washingtonia filifera growing deep in a cleft. This

particular plant, from the northeastern plateau, does indeed offset, making a dense colony of nearly powder-blue,

jaggedly pointed leaves and rosettes to about 18 to 24". A notoriously water sensitive species, adapted to both

winter and summer rainfall but not much of it. Should be kept in very gritty soil or in container, but its sensitivity is

well worth accommodating. Not as frost hardy as some, we expect 10º to 15ºF if dry.

Agave difformis

This is a more upright form of A. lophantha from a bit further south in Mexico forming clumps, each rosette to

about 10” and very symmetrical with leaves blue-green above -- often centered in a creamy green -- and lighter

beneath. We were suspect at first of this plant’s frost hardiness but it has performed well in our garden and we have

rosy reports from the USDA zone 7 garden of Tony Avent in North Carolina. Provide more protection under 15F

where winters are wet. Very good container plant.



Agave durangensis

A most beautiful species with upright, narrowly fluted, and very blue leaves. Occurs in only scattered locations

above 5,000 ft in the Sierra Madre Occidental in, yes, Durango, Mexico. This form collected at 8,100 ft -- almost

directly on the Tropic of Capricorn -- from a ridgetop colony amid small oaks, junipers and pinon pines, very near

the southernmost colornies of A. parryi. So far these plants, with good drainage and bright sunlight, have withstood

temperatures of about 20F and would probably withstand low to mid teens if protected from excess winter wet.

Agave felgeri

Found by and named for friend and botanist, Richard Felger, and inhabiting dry, stony hills of western Sonora (the

plant, not Dick), this rare A. parviflora relative has more robust leaves and rosettes. Clumps of multiple rosettes

--no more than 8" tall -- of triangular gray-green leaves adorned with white markings and abundant cobweb-like

filifers. A fine pot plant and happy in garden situations if provided excellent drainage. Frost hardy to between 15º

and 20ºF, mid to upper USDA zone 8 -- the drier the better.

Agave flexispina

Rare in cultivation this agave comes from oak and grasslands of northern Sonora in Nexico. Up to 18” tall with

silvery gray leaves, offsetting occasionally after becoming settled. Very drought tolerant but responds amicably to

summer water if soil is very well-drained. Frost hardy in upper USDA zone 7 with reports surviving 0F unharmed.

Think drainage!

Agave geminiflora

A rare relative in the Agave filifera group, this southwestern Mexico native has intriguing deep green rosettes of

rubbery, somewhat weeping leaves and can even produce a short trunk. Enchanting silver-white filifers toward the

center of the rosette. A tender species damaged under about 20ºF, USDA zone 9, it is best in a tall pot where its

weeping foliage can spread out and over the rim. When the plants reach 1 ft. or more in diameter, they produce a

spike of flowers well over 5 ft tall at which time, hopefully, they will produce an offset or two.

Agave gentryi

A mountaintop species, failrly widespread in northeastern Mexico but seldom seen....because it grows on

mountaintops. We first spotted this plant,via binoculars, in what appeared as utility poles,one growing above even

the nearby oaks and pines. These were, indeed, the red stems of the over 15-18 ft flowers stalks! Though sharing

habitat at its lower elevations and creating wonderful hybrid forms, the typical species grows into shiny deep-green

rosettes, each individual measuring 6 ft+ before sending up enormous flower stalks. Another resilient species,

tolerant of dappled shade where winters are not too wet and loving ample moisture with good drainage. Has

proven hardy to even a few degrees below 0F but would suggest overhead coverage at those temperatures.

Possibly the largest very hardy agave.



Agave gentryi - blue form

One of several closely related taxa from the Sierra Madre Oriental of northeastern Mexico, these from seed

collected high, above 8,000 ft in the Sierra La Peña. The silver-blue leaves form a rosette of up to 4 ft, making for

a dazzling container or garden specimen in sun to light shade and very well-drained soil. One of the least fussy

agaves, this seed collection indicates hardiness of 0º to 10ºF; so far having withstood upper single digits in Tony

Avent's garden in North Carolina. Woo hoo!

Agave gentryi 'Jaws'

From an intriguing group in an even more intriguing part of the world, northeastern Mexico's Sierra La Peña, a

floristically rich part of the world. Three agaves inhabit the upper slopes from 8-9,000 ft, this one now being

settled on the species A. gentryi. Beautiful gray-green rosettes of sharply pointed leaves with jagged serrations and

embossed impressions of the older leaves on each emerging new. This selection was made by the Yucca Do boys

in the early 1990s and has been very slow to offset. To about 24-36" or more eventually, this selection, found amid

pines and oaks in light shade on rubbly limestone outcrops, has taken a myriad of garden conditions. Quite happy

in dappled shade but beware of wet leaves sitting in the crown in winter. It is exquisitely beautiful for the deeply

indented leaf margins and double, reddish teeth. So far, unharmed in upper USDA zone 7 winters.

Agave gentryi [La Encantada]

Recently introduced, this high mountain century plant, rather large-growing, to 5 ft or more, has bold, deep

gray-green leaves forming large single rosettes before pupping. Eventually produces a red-stemmed flower stalk

approaching 20 ft tall!. Perfect windowsill plant – NOT! This form appears to have had some dealings with

nearby A. scabra as it has a bluish cast to the leaves not often found in the species. Quite capable of enduring

garden water and partial shade. Frost hardy at 10 to 15F, bottom of USDA zone 8. Otherwise a wonderful large

container specimen.

Agave gentryi x montana

Collected originally in the Sierra Madre Orientale of northeast Mexico in an area where the majestic A. gentryi

meets the more refined and smaller A. montana. The most beautiful silver-gray color represented here suggests that

A. scabra, the universal partygoer of that region, has come along for the ride as well. To 4 ft wide, this stunning

plant is tolerant of garden moisture --provided drainage is good -- and prefers full sun for best color. Cold hardy to

10F - USDA zone 8. Fast growing.

Agave gracilis 'Guadalupe'

The name A. gracilis is loosely applied to a group of plants in northwestern Texas into New Mexico, the result of

natural hybrids between A. lecheguilla and A. neomexicana. This particular clone makes a narrow-leaved,

blue-gray rosette with attractive horizontal striping, each plant measuring about 12” then offsetting to make a dense

colony if allowed. Bright light and average to gritty, well-drained soil. Originally collected on the east side of the

Guadalupe Mountains in southeastern New Mexico at 6200 ft making frost hardiness probable well into USDA

zone 6.



Agave 'Green Goblet'

A form selected in the high Sierra Madre Orientale of eastern Mexico by Carl Schoenfeld and Wade Rosch. This

plant is likely A. gentryi with a little A. montana thrown in and forms 4-5 ft rosettes of fleshy, moss-green leaves

beautifully patterned and indented. From pine/oak woodland, it is adaptable to moist soil and even partial shade

where autumn leaves won't collect in the rosettes. Thus far has been hardy to close to 0F, USDA zone 7. However,

the colder the climate, the more sun and drainage should be provided.

Agave havardiana

One of the best and hardiest agaves, with olive-green, often dusty-blue curving leaves in the classic agave shape.

Big, robust, and wickedly spined. Usually a solitary rosette, though sometimes with pups. 2 ft tall and wide. Best

with good drainage. Full sun. Hardy to -10F or less, USDA zone 6 or lower. Texas, New Mexico, and Coahuila,

Mexico.

Agave ‘Kissho Kan’

Stunning blue-gray leaves edged in white make this symmetrical rosette an outstanding addition to any collection.

Yellow leaf spines darken to reddish brown adding distinction. To 15” tall x 18” wide and slowly offsetting. Needs

light, and well-drained soil. Frost hardy to USDA zone 9, so best in container protected from winter wet where

temperatures drop below the 20s F.

Agave lophantha var. funkiana

This variant of the popular A. lophantha occurs from Zacatecas north into Nuevo Leon, Mexico with narrowish

leaves, to 18", marked green and white with a healthy dose of blue (that's the funky part). Offsets to form a small

colony. Prefers very well-drained soil and temperatures not below 15 to 18F, though has survived considerably

lower when dry and has recovered from close to 0F, bottom of USDA zone 7. A most appealing container

specimen.

Agave macroculmis

High elevation seed collection from Mexico. Dwarf semi-running agave. Excellent for rock gardens, walls,

containers. Full sun, sharp drainage. Will stop bicycles cutting across your parking strip. Cold hardy to 10-15F -

lower USDA zone 8, possibly colder with excellent drainage.

Agave macroculmis YD 129

From several places in northeastern Mexico, this collection, from mountain ranges north of Potosi from nearly

7000 ft in oak, pine, and yes...douglas fir, forms colonies of 4 ft rosettes tinted a lovely blue-gray and showing the

leaf scars to beautiful effect as each new leaf emerges. The leaf margins are undulating and decorated with dark

spines. So far these have proven frost hardy to the low teens F, low to mid USDA zone 8, and are quite happy with

abundant garden moisture so good drainage and air circulation in the winter is helpful. Fine pot specimen.



Agave (Manfreda) 'Spot'

A Cistus introduction from one of our hybrids between A. virginica and A. maculosa. Forms stunning rosettes to

about 18", with blue-green leaves endearingly adorned with purple spots. Though tolerant of some drought prefers

a medium to moist situation. Light shade to full sun. Deciduous at 25F (don't worry, it's supposed to do that. )

Cold hardy to -20F, USDA zone 5 or below, if placed in well-drained soil.

Agave mckelveyana - garden form

Shared with us by rock gardener Phyllis Gustafson, this vigorous clone has provided many hours of entertainment

to those attempting to weed oxalis from between its lovely leaves. A vigorous rock garden plant, the 6" dark blue

leaves make compact and spreading clumps and are perfect with other rock garden plants or in bowls as pot

specimens. Has proven hardy in gardens to -5ºF, mid USDA zone 6, provided good drainage.

Agave mckelveyana SBHMPS 6690

Our seed collection from the Hualapai mountains of northeastern Arizona, this quickly multiplying agave, related

to A. deserti, produces multiple 6-8" rosettes of silver-blue leaves with backward pointing spines. Wonderful in

rock gardens or as a filler among other larger plants. One of the hardiest to cold, to -10º F, USDA zone 6, and

resilient to excess garden moisture provided excellent drainage. Full sun to dappled shade in hot places.

Agave montana

One of the most sculptural century plants from high elevations in Mexico, this is often sandwiched between the

larger, higher elevation Agave gentryi and the lower elevation Agave scabra and can show characteristics of both

growing with pines and oaks. 1.5-2 ft, heavily toothed rosettes are deep olive-green brushed with blue. Accepts

average garden moisture provided excellent drainage. Sun; adapts to partial shade. 0 to 10F.

Agave montana ‘Baccarat’

A selection by Yucca Do Nursery from high elevation in Mexico’s Nuevo León Province, named after a fine

crystal because of the leaf imprints on the backs of glaucous leaves that end in spiny black tips - very dramatic.

Striking clumps to 2 ft tall x 3 ft wide. Sun, lean soil, and good drainage. Frost hardy in upper USDA zone 7.

Agave montana [LaPeña, NL, Mex.]

One of the most sculptural century plants, this form from high elevations in the Sierra LaPeña in Coahuila grows

among pines and oaks. The heavily toothed, 18" to nearly 2 ft rosettes are deep olive-green gently brushed with

blue and retain imprints of the leaves and spines with which they were once nestled. A garden tolerant species that

takes average garden moisture in stride provided excellent drainage and is adaptable to partial shade as long as it

doesn't become smothered by falling leaves. Should be hardy to between 0º and 10ºF.



Agave 'Mr. Ripples'

Yes, the leaf edges are wavy on this lovely agave, an introduction by Yucca Do Nursery, possibly a cross between

A. salmiana and A. protoamericana. Forms single rosettes to 3-4 ft tall x 4-6 ft wide, the toothed green leaves with

a bluish tinge and velvety texture. Full sun with good drainage and little summer water. Frost hardy to 0F - USDA

zone 7.

Agave multifilifera

A favorite around the nursery where it is compared to a hairy fire hydrant. Tight leaves with lots of white filifers.

Stiff, short and sturdy. This high elevation seed collection hardy to 20F or less - upper USDA zone 8, bottom of

zone 9..

Agave multifilifera ‘Hairy’

One of the most exquisite small agaves with rosettes only 8" to a foot in diameter with narrow leaves marked

starkly white, this form chosen by Mountain States Nursery for its abundant white filifers enhancing the striking

look of the plant. Not particularly fussy; any well-drained garden spot with sun where temperatures seldom drop

below 16 to 18 F, upper USDA zone 8. One fine container specimen!

Agave murpheyi

Sweet little agave, from mid elevation deserts of central Arizona into Sonora, often found associated with Native

American sites. To 18", or 2 feet at most, with narrow, upright leaves, slightly recurved and steel to powder blue.

Offsetting fairly quickly. The eventual flowers also produce tiny bulbils -- as the song goes -- which might explain

its being spread by people in the early days. Because of its drier habitats we keep ours in pots with very well

drained soil, or only in the most exposed areas of our garden and growing in true grit. Full sun. Again, dry

conditions with an occasional splash of summer water. Cold hardy into upper USDA zone 7 if dry.

Agave murpheyi ‘Variegata’

Sweet little agave, from mid elevation deserts of central Arizona into Sonora. To 18" to 2 ft. Narrow, upright

leaves, wavy with creamy yellow margins, the centers steel to powder blue. Offsets quickly. True grit in pots or

exposed garden areas. Full sun. Dry conditions with a bit of summer water. Upper USDA zone 7 if dry.

Agave neomexicana

A tough-as-nails species closely related to A. parryi but with narrow leaves held upright and out. Deep blue

adorned with brownish red spines. Slowly forming colonies. One of the hardiest species; to -20ºF, USDA zone 5,

with good drainage.



Agave ocahui

This symmetrical and architectural century plant from Sonora -- to under 18" to 2 ft with shiny forest-green leaves

and cream to mahogany edges -- is underutilized in both garden and container. The flowers stems are quite narrow,

to 12 ft or more in height after several years, but it is really the unusual rosette we are after. Our favorite specimen

is in a deep brown Chinese urn that reflects the color of the leaf margins. Low to medium nutrients maintain

compact growth. This collection, by Greg Starr from one of its northern sites a few miles south of the Arizona

border, has been frost hardy to nearly 10ºF with good drainage. Protect in containers below upper USDA zone 8.

Agave ornithobroma

Wonderful, short-trunk forming species from subtropical western Mexico, these collections from Sinaloa at under

500 ft elevation -- did we say warm? Closely related to A. geminiflora, the 18" rosettes, with extremely narrow,

flexible leaves of dark green, are beautifully framed by a gazillion curly white filifers or hairs. Quite happy with a

fair amount of moisture; winter drought decreases chance of problems. We have had this in our garden, hardy for

the last few years with luck. Really, it should be protected below the mid 20ºs F so best for mildest parts of the

world or as fabulously small-scale container plants. USDA zone 9/10. Full sun to dappled shade in a bright

window, or your nearest lava outcrop.

Agave ovatifolia

One of the most beautiful century plants, found in the Sierra de Lampazos in the early 80s by the late great

plantsman, Lynn Lowrey and only named in 2004 by agave-ist Greg Starr. Growing in a limited range of

pinyon/juniper/oak country above 8000 ft, the exceedingly wide, beautifully toothed and chalky blue rosettes can

reach over 5 ft in width giving the appearance of a much more tropical species. Has proven to be one of the best

performers where cold and wet is experienced in winter and has, thus far, proven hardy to 0F, USDA zone 7, or

even a bit lower. Sun to dappled shade; drainage is always a plus.

Agave ovatifolia [Sierra de Lampazos clone]

One of the most beautiful century plants, found in the Sierra de Lampazos in the early 80s by the late great

plantsmen, Lynn Lowrey and only named in 2004 by agave-ist Greg Starr. Growing in a limited range of

pinion/juniper/oak country above 8000 ft, the chalky blue rosettes, exceedingly wide and beautifuly toothed, can

reach over 5 ft in width giving the appearance of a much more tropical species. Has proven to be one of the best

performers where cold and wet is experienced in winter and has, thus far, proven hardy to 0F or even a bit lower.

Sun to dappled shade; drainage is always a plus.



Agave parrasana

This Mexican species is most easily identified by its thick triangular leaves -- beautifully marked blue-green in

color -- arranged in a striking rosette and edged with equally thick brown and white spines. Plants form low dense

mounds, each rosette being under 6" in height and 1 ft in width. Less frost hardy than some, the low to mid teens F

seems to be the limit of frost tolerance. Mineral soil, sharp drainage and full sun. A fine pot plant. Each rosette

eventually measuring 2 ft x 2 ft and in time sending up 12 ft branched flower spikes of warm yellow blushed

apricot. This represents a high elevation collection at over 8,500 ft that has thus far withstood between 0 and 10F,

USDA zone 7, with overhead protection from excess winter moisture. Stunning pot plant or container specimen.

Agave parryi (aff. var. couesii) SBHMPS 6725

From one of our favorite places in Arizona, east of Prescott amid nolinas and ponderosa pines, this extremely hardy

century plant grows in colonies of giant (nearly 2 ft) blue, artichoke-like rosettes. Its habitat is a cold climate where

temperatures frequently drop below 0ºF and the ground is snow covered or frozen for long periods of time. These

plants should be hardy to well below -10ºF, USDA zone 6. Although this population exhibits characteristics of both

A. parryi and A. couesii, what we know for certain is that these beautiful blue plants are from the highest elevation

we have ever found the species and should be exceedingly frost hardy.

Agave parryi (aff. var. couesii) SBHMPS 6728

From the high ponderosa woods at over 8,000 ft between Jerome and Prescott, Arizona, where, in 1981, we first set

our eyes upon this particular "patch" growing in light shade with beautiful, 24", blue "artichokes" and dozens of

offsets spreading from the plants, seemingly in a race to get to a nearby clearing. Sometimes the reason the plants

are brought into cultivation is simply because they are easy to propagate. This little agave is both beautiful....and

we can make more. The same culture as for other Agave parryi with dappled shade to bright light and fairly free

drainage. This clone, however, should be exceedingly frost hardy to at least -10ºF, USDA zone 6, possibly colder.

Should still be provided winter protection if grown in container below USDA zone 8.

Agave parryi ‘Cream Spike’

Stunning Mexican agave with creamy white edging on the blue leaves. To 6” tall and, eventually, 1 ft wide. A

striking presence in the dry garden. Likes full sun and occasional summer water pretending to be thunderstorm.

Reported to be frost hardy in upper USDA zone 7. Good in pots elsewhere.

Agave parryi [N. of Sedona, AZ]

Tightly clumping agave with seriously impressive leaves and extremely sharp spines. This form, to 3 ft tall and

wide, found north of Sedona, Arizona. Best in full sun with excellent drainage. Allow to dry in winter. Classic

playground plant. Cold hardy to 0F - USDA zone 7.



Agave parryi var. huachucensis

From, yes, the Huachuca Mountains in southern Arizona and into northern Sonora, this beautiful gray/blue century

plant forms a classic 20-24” artichoke shape, eventually offsetting to form small colonies. From mid-elevation

(5-7000 ft) this, though not the most frost hardy of the parryi clan, takes 10 to 15F in stride, mid to upper USDA

zone 8 -- lower if very well drained. Full sun and summer water in Mediterranean areas.

Agave parryi var. huachucensis 'Huachuca Blue'

A Cistus introduction, bluer than its near relation. Our fabulous selection -- from 7000 ft in the Huachuca

Mountains in southern Arizona and into northern Sonora -- exhibits particularly steel-blue leaves in the classic

20-24” artichoke shape, eventually offsetting and forming small colonies. Though not the most frost hardy of the

A. parryi clan, still takes 10 to 15F in stride, mid to upper USDA zone 8, and lower if very soil is well drained.

Full sun; provide summer water in dry areas.

Agave parryi var. truncata

Arguably the most beautiful form of the species but also the least hardy. Wide, blue, truncated leaves -- think giant

pine cone. Good drainage and the brightest light is best to maintain shape. Possible in the ground where

temperatures seldom and only briefly dip below 15ºF, mid USDA zone 8. Otherwise makes a fine container

specimen.

Agave parryi var. truncata - Gentry form

Arguably the most beautiful form of the species but also the least hardy. This one from Howard Gentry, master of

agaves. Wide, blue truncated leaves -- think giant pine cone. Good drainage; the brightest light to maintain shape.

Best where temperatures dip below 15ºF - mid USDA zone 8 - seldom & briefly. A fine container specimen.

Agave parviflora [Cochise Co. AZ] SBHMPS

Our collection many years ago from the rich grasslands of southern Arizona. 6" rosettes of deep green leaves

marked white and with white threadlike filifers -- the plants slowly offsetting to make dense clumps. Narrow

flowering stalks with tinted red flowers. A jewel-like plant -- it's true! We separate our clumping plants as we find

them most attractive as singles and, of course, so we have enough to share. Lovers of summer moisture and winter

drought, they perform admirably outdoors in our Portland garden and are exquisite container plants. We find that

rather low fertility keeps them from looking stretched. Bright light also helps. Hardy to close to 0ºF.



Agave parviflora [Ruby, AZ]

A jewel-like miniature agave from the dry grasslands of southern Arizona and adjacent Sonora, a habitat that

includes Dasylirion wheeleri and the famed Opuntia violacea v. santa rita. And, in this particularly area, we have

selected forms of Heucheras, Zauschneria arizonica, and numerous desert ferns. Rosettes of only 6- 8", and narrow

leaves, deep green marked white, with curled filifers make it an intriguing plant for container or garden. The

flowering stalks are tall and narrow; the unusual, creamy flowers tinted red, make the hummingbirds very happy.

The habitat has dry winters and thunderstorm laden summers so these plants are best well watered in summer with

excellent drainage and kept dry in winter, although plants in our Portland garden have been quite happy for some

years in a stone wall with no cover. Bright light to only the lightest of shade for best form. Frost hardy from 0 to

10F, USDA zone 7; colder if kept winter dry.

Agave parviflora ssp. flexiflora

Another rare plant from southeastern Arizona and south with small jewel-like rosettes of under 6" consisting deep

olive-green leaves marked white with occasional filifers and narrow flower spikes tinged red. Occasionally

offsetting -- rather than off-putting. Accepts average moisture if the soil is well-drained. Frost hardy at 12º to 15ºF,

to mid USDA zone 8.

Agave petrophila

Another limestone endemic century plant with abbreviated, quill-like, blue-gray leaves dusted pink with drought.

Denizens of tiny crevasses and growing only to about 6” in width, A. petrophylla is a jewel-like addition to the

garden or container collection. As its habitat would imply, excellent drainage is helpful with lean soil. Winter

drought is also preferred. Frost hardiness only to the low 20s. Full sun to only slight shade.

Agave polianthiflora

Tiny agave with flowers resembling a tuberose. Often 1 ft or less. Rare in horticulture, but has taken 21F without

damage. If you tire of growing it, roast it for a sweet tasting delightful meal. Lots of sun and good draiinage. Frost

hardy in USDA zone 8 and possible lower.

Agave ‘Ruth Bancroft’

From the hills near Saltillo, Coahuila, Mexico, where 3 century plants converge if not collide, this from the

Bancroft garden has an exquisitely fine, platinum-colored sheen with no white markings -- clearly showing its A.

victoria-reginae and A. scabra parentage. Bright sun. Great in containers. Cold hardy to 10F or so, USDA zone 8.

Also known as A. ‘Sharkskin.’



Agave salmiana

A large plant from north to northeastern Mexico and one of the hardiest of the big century plants. Silvery blue

leaves. To 5 - 6 ft -- smaller if kept root bound -- and eventually offsetting, making a fine specimen or focal point.

Unusually garden water tolerant though excellent drainage and good air circulation are helpful. Has survived 0º to

10ºF but suggest covering for protection below 10º to 15ºF just in case. Wow!

Agave salmiana var. ferox

Huge, scary agave to 7 ft with an urn-shaped silhouette and foot wide, gray leaves. Common in Mediterranean

gardens as an accent that rarely flowers. Cold hardy in USDA zone 9, to 20-25F. Good for containers.

Agave scabra

Native to north central Mexico and into west Texas, this very rough leaved and silver-blue species can grow to 3-4

ft, with long upward pointing narrow leaves. It will eventually clump. Quite tolerant of summer monsoons, they

require well drained soil, especially in winter. Our plants represent seedlings from northern colonies where

temperatures of 0ºF are not uncommon. One of the hardiest of the large agaves.

Agave scabra x victoriae-reginae SBH 0722

One of Sean's early collection from December of 1983 in the mountains northeast of Saltillo, Mexico in an area

where these two species collide making a wonderful array of hybrids known in the trade as A. fernandi-regis. This

collection has the bold upright leaves of Agave scabra, dark gray-green with, indeed, a scabrous texture, and the

bold, white markings of the A. victoriae-reginae, but few and wider. We affectionately call it "clone 1". This is

actually our first division after...ohmygod!...22 years. These should be hardy to 10ºF or even a little lower if dry.

Very architectural pot specimen.

Agave schidigera 'Shira ito no Ohi'

The cultivar name, NOT "Honey I shrunk the kids", refers to the silky threads or filifers that decorate these

rosette-forming agaves, solitary plants to 18" tall and wide, the dark green leaves strikingly variegated with creamy

margins and quite symmetric filifers that add to the show. The species, from the high country of Mexico's Durango

State, shows a decent tolerance for moisture and frost in USDA zone 8. But temperatures below 20F, bottom of

USDA zone 9, can mark the beautiful variegations so we recommend a moveable container.

Agave shrevei ssp. magna ‘Dentata’

From the mid-elevations of Sonora (3000 ft), this tender agave was selected for its massive size and massive

toothed leaves. Best in a container where it can sit the wet winter out indoors. Full sun, normal water in the

summer. Extremely uncommon.



Agave 'Silver Surfer' YD 45-83

From a 1992 seed collection introduced by Yucca Do Nursery from the mountains above Palmillo, Tamaulipas,

Mexico. Probably a hybrid of A. scabra x A. americana ssp. protoamericana, this clone, selected by fellow agave

geek Tony Avent, exhibits an almost bead-like, silvery cast on deep blue leaves. Sweeet! Sun and good drainage,

of course. Expect at least 4 x 5 ft in climates not falling below 15F though has recovered quickly from below 10F,

upper USDA zone 7.

Agave striata

Extremely tough with numerous closely held offsets making an impenetrable mass. Effective in parking strips

where you don’t want car doors opening. 3 ft tall and wide. Tall spikes of yellow flowers in late summer. Full sun.

Cold hardy to 15F - mid USDA zone 8.

Agave striata - Espadina form

Found in the wilds of northern Mexico, a symmetric plant that clumped in what appeared to be piles of

tumbleweeds from a distance. Grows to about 18” x 18” with leaves tinted blue, often tipped purple-pink in full

sun. Water sensitive - needs great drainage. Hardy into the upper teens. Sun. Cold hardy to 16F - mid USDA zone

8.

Agave stricta

Wonderfully symmetric, multi-leaved rosettes to about 18" or a little larger and eventually offsetting. The leaves

are pleasing blue-green with a purple tint. Preferring mineral, well-drained soil and bright light, these plants have

remained hardy, where dry, to 15ºF, mid USDA zone 8, or below.

Agave stricta - dwarf form

From central northern Mexico at mid elevations and appearing as little, blue-green sea urchins, to 6-10". A fine

addition to a detailed area of the garden where moisture can be controlled and temperatures are not likely to drop

below 18º to 20ºF, upper USDA zone 8, for any length of time. Otherwise a striking, small container plant for

bright light.

Agave titanota

Striking and rare species of southern Mexico with 18" to 20" rosettes of thick, triangular, steel-blue leaves edged in

sweeping and swirling white and copper colored spines. Though hardy only to about 20ºF, it is a striking pot plant

in frost prone places.



Agave toumeyana [Fish Creek Hill, AZ]

These plants represent old seed collections from C&J Nursery. A colonizing plant from higher elevations of

Arizona, it quickly forms a colony of 5-6" rosettes of narrow leaves edged and streaked white with filifers and

sharp tips. Plants have proven frost hardy to 0ºF, USDA zone 7, with excellent drainage but might be protected at

10º to 15ºF, zone 8, just in case. Fine pot plant.

Agave toumeyana var. bella

A rare and unusual plant with particularly dense rosettes and striking white markings. A colonizer from high

elevations of central Arizona, it makes a fine rock garden specimen if excellent drainage and bright light can be

maintained. Protect especially from excess winter moisture. Has withstood -10ºF, USDA zone 6, or below in dry

soil.

Agave utahensis [Mt. Trumbull, AZ]

Once described as A. u. var. discreta, these produce beautiful rosettes of blue-green leaves edged with ivory to

brown corky spines. Each rosette becomes 10-12" & begins offsetting in a couple of years. Frost hardy to 0º to

-10º F - USDA zone 6 - with reeeeeeeally good drainage (they grow in the tiniest fissures ) and very bright light.

Agave utahensis [Peach Springs, AZ]

Representing what was once described as A. utahensis v. discreta, plants originally from these colonies produce

beautiful rosettes of blue-green leaves edged with corky spines from ivory to brown. Each rosette becomes 10-12"

and begins offsetting in a couple of years. Though frost hardy to at least 0º to -10º F, their habit of growing in the

tiniest fissures, nearly free of soil, tells us they need reeeeeally good drainage and very bright light.

Agave utahensis ssp. kaibabensis SBHMPS 6747

From the Tuweep area on cliffs and mountaintops on the northern edge of the Grand Canyon abyss amid junipers

and beautiful red rocks....and far away from restaurants that serve alcohol..... I believe this colony to be under the

form kaibabensis -- a particularly wide and long leaf form of the highly variable Utah agaves with nearly 18”

rosettes of a cheery blue-green and dark, evenly set spines. These plants offset rather sparsely to make attractive

clumps rather than colonies. After 10 years or so, flowers spikes rise to nearly 10 ft. Though one of the most frost

hardy agaves, they do like their drainage, so in areas of high moisture, best placed in stone walls or under cover.

Cold hardy to about -20F, USDA zone 5. Good container plant anywhere.

Agave utahensis v. eborispina

Exquisite form: the most northern Agave anywhere. 6-10” rosettes of chalky blue leaves with ivory corkscrew

spines, sometimes black-tipped. Ooh! Bright sun with very good drainage. Perfect for your limestone crevice.

Hardy to well below 0F - USDA zone 7. (Did we mention really really good drainage?)



Agave utahensis v. nevadensis SBH 6882

From a group of plants in northeastern Saltillo, Mexico where these two species merge comes a form long known

as Agave fernandi-regis. This collection, Sean's from December of 1983, represents one of this spectrum of

hybrids. 8" lead-colored rosettes have striking white markings, the plants slowly offsetting to form a colony.

Because these grow in sharply drained limestone, they would prefer lean conditions at your home. Hardy to 10ºF

or even below with winter protection from wet where necessary.

Agave victoriae-reginae

Beautiful agave from N. Mexico. Olive-green rosette of blunt black-spined leaves marked with wide silvery white

striations. Slow growing to 18” tall and wide, offsetting slowly. Rated to 12ºF - bottom of USDA zone 8; has

survived in dry winter places, e.g. Denver, CO, to well below 0ºF. A beautiful pot specimen.

Agave victoriae-reginae 'Porcupine'

This selection from Yucca Do Nursery has indeed porcupine quill-like leaves with with gentle patterning on a

symmetric plant making it a more dazzling version than the typical Agave victoriae-reginae. Bright light, good

drainage, and, preferably, winter dry. Frost hardy to below 10 to15F, mid USDA zone 8, depending on moisture.

Agave victoriae-reginae var. compacta

A beautiful compact form of an ever-popular species. Each olive green rosette consists blunt, black-spined leaves

marked with wide, silvery white striations. Each rosette grows to about 6" or less in width, clumping after a year

or two. One of the hardier species, originally from near Saltillo in northern Mexico, it has been rated to 10ºF,

USDA zone 8, but has survived in dry winter places such as Denver to well below 0ºF, zone 7. If this makes you

nervous, it makes a beautiful potted specimen.

Agave weberi 'Arizona Star'

A most fortunate find at Mountain States Nursery of this 2 ft, round, blue-green century plant with soft leaves (for

the genus), this clone streaked and edged creamy yellow. Vigorous and hardy to 15F or so, mid USDA zone 8. Best

kept dry in winter. Fabulous container plant. Very easy care. Provide some summer water and bright light in the

garden.



Agave x arizonica - cl 1

Wonderful endemic from central Arizona, almost undoubtedly a natural hybrid, originally from only a few

individual plants growing among chaparral in miniature oaks and manzanita. This is a selection given to us by the

late agave God, Howard Scott Gentry, and of great ornamental and sentimental value to us. Fairly slow growing

rosettes, to 12" or so with glossy green leaves edged in mahogany, slowly forming a colony to a couple of feet

across. Beautiful for rock garden, dry stone wall or container. Not particularly fussy about moisture, though

careful drainage and bright light are always a plus, and drier winter conditions can add several degrees of frost

hardiness. So far undamaged between 5º and 10ºF and very slow growing. Survived in our high desert, eastern

Oregon garden a -12ºF dip in 1990, this under bone-dry conditions.

Agave x arizonica - cl 2

Wonderful endemic from central Arizona, almost undoubtedly a natural hybrid, originally from only a few plants

growing among chaparral in miniature oaks and manzanita. This selection, given to us by the late agave God,

Howard Scott Gentry, is of great ornamental and sentimental value to us. Fairly slow growing rosettes, to 12" or so,

with glossy green leaves edged in mahogany, slowly forming a colony to 2 ft across. Beautiful for rock garden, dry

stone wall or container. Not particularly fussy about moisture, though careful drainage and bright light are always a

plus, and drier winter conditions can add several degrees of frost hardiness. So far undamaged between 5º and

10ºF, mid USDA zone 7. Survived in our high desert, eastern Oregon garden a -12ºF, upper zone 5, dip in 1990,

this under bone-dry conditions.

Agave x ferdinandi-regis

This little century plant comes from one of the more exciting habitats in agaveland, a series of mountains northeast

of Saltillo in northwestern Mexico where the beautiful A. victoriae-reginae crosses with both A. scabra and A.

lechugilla. The form of this plant is particularly upright, its leaves marked white with a pinkish gray cast and

topped with black spines. Reaching 12-18" and offsetting freely, it is hardy to between 0 and 10F, USDA zone 7,

with excellent drainage. Full sun. Excellent pot specimen.

Agave x ferdinandi-regis 'Saltillo Splendor'

A Cistus introduction. From the famed hills west of Saltillo, Mexico where several species of century plant

integrate creating, most beautiful hybrids, our collection from December 8, 1993 as a single pup that has slowly

increased over the years. Very symmetric, gray-green leaves having the texture of suede with bold white streaking

and three prominent black tips. Has been frost hardy to at least 12F, lower USDA zone 8, if winter dry; otherwise

very good rock garden/wall or container plant



Agave x gentryi

Shared with us by Yucca Do and Plant Delights nurseries, this recently named species is very possibly a natural

hybrid. This high elevation collection from southeastern Nuevo León at 9,500 ft might well represent this plant in

its purest form. Growing to nearly 3 ft tall and even wider, the glossy green leaves with upturned tips and very dark

spines make it a very striking garden or container plant. We estimate hardiness as low as 0º to 10ºF, USDA zone 7,

with good drainage.

Agave x leopoldii

Compact and most architectural century plant brought to us by Yucca Do Nursery with narrow, slightly curved

leaves, a gray-blue-going-green sheen complete with a few stripes and polka dots. Will eventually offset. A most

attractive, small container plant, rarely growing more than 18” and a great addition to the dry or rock garden in a

sunny site with gritty soil. Frost hardy in USDA zone 8, to 15F or so and as low as 10 if protected from overhead

moisture.

Agave zebra

From north central Mexico, this beautiful plant, with narrow leaves to 4 ft striped silver-blue and olive-green,

makes a stunning pot or garden specimen. Though the plant does occasionally offset, offspring might be removed

not only to propagate the plant but also to maintain the presence of an individual and solitary specimen. Not from

as high elevation as some, A. zebra seems quite happy into the upper teens F but can receive frost damage below.

Winter drought or cover extends its hardiness lower. Best in full sun with excellent drainage.

Beschorneria albiflora

One of the larger members of this genus of Agave relatives from northeastern Mexico growing amid oaks, pines,

and many other delicious plants. This species forms open rosettes of pale green leaves, to about 3 ft, with flower

stalks rising to 6 ft or more, the flowers often red at the base and very pale green, indeed nearly white, at the tips of

the sepals. Prefers some summer water where dry. Has performed admirably in our garden in dappled shade and

should be frost hardy in USDA zone 8, to about 15F with no leaf damage, resprouting in spring from 10F or so.

Beschorneria decosteriana

One of the more robust species of this agave relative, this collection is from the high mountains of northeastern

Mexico, growing in the shade of oaks and pines. 5" wide leaves in rosettes, each stretching to over 3'., and flower

spikes 6'. tall or more with astoundingly red stems, red and green flowers, and pink-blushed seed pods! Drought

tolerant but loves a little summer water. A bold-textured garden plant in dappled shade to full sun where

temperatures seldom drop below 15ºF. The plants have recovered quickly from temperatures as low as single

digits provided good drainage and a wee bit of overhead protection.



Beschorneria ‘Ding Dong’

Straight from Tony Avent’s garden to yours, this Beschorneria hybrid was selected for its “truly huge proportions.”

3’ wide massive green sandpaper-like rosettes and 7’ giant, asparagus shoot, flower spikes topped with bell-shaped

flowers of red and green. Simply obscene. For sun to part shade. Zone 7-10.

Beschorneria septentrionalis

Another bold non-agave from northeastern Mexico, producing rosettes to 2 ft of deep green, 4" leaves, the plant

resembling a pile of hung-over starfish. The flowering stems and flowers are deep red; the flowers edged with

green followed by red tinted seed pods. Drought tolerant but loves a little summer water. Excellent drainage;

partial shade to full sun. Essentially a USDA zone 8 plant though success has been achieved in USDA zone 7

gardens with occasional protection.

Beschorneria sp. [S. LaPeña, Mex. 8700']

From a 1993 collection in the rugged mountains of Coahuila, Mexico amid many other botanical treasures, comes

this strap-leaved, blue-green perennial to only about 18” with some of the prettiest flowers to be found in the

genus. The stems are red, holding orange red flowers with bases dipped in green. Hummingbird magnets! We are

still looking for a likely name. Because of its high elevation habitat at over 8500 ft, it is expected to be frost hardy

well into USDA zone 7 and evergreen to 15 F. Full sun to medium shade; has succeeded in full shade in very hot

climates with occasional summer water for best look. A very nice plant.

Beschorneria yuccoides

Take a walk on the wild side with this Mexican agave relation. Called coral yucca in the southwest, this evergreen

clumper is stunning when its 6 ft stalks of coral red flowers emerge in summer. Hummingbirds delight! Well

drained soil! and sun. Frost hardy to 15F, mid USDA zone 8.

Beschorneria yuccoides x decosteriana

3' rosettes with deep green leaves dusted powder blue. 6 ft spikes of green and red flowers. Cold hardy Hardy to

10F, USDA zone 7, bottom of zone 8, but recovers from colder. Sun to part shade.

Dasylirion acrotrichum

Big bad robust sotol from northern Mexico, totally hardy in the Pacific Northwest. Achieves a 4 ft trunk with age

and a perfect rosette of 3 ft long, pale green leaves with yellow spines. The flower stalk reaches to 15 ft. Full sun

and perfect drainage. Deer (and other mammal) resistant. Frost hardy in USDA zone 8 or lower with proctection.



Dasylirion aff. leiophyllum

Closely related to the smooth-leaf sotol, this form from Mammalique, Cohillo Mexico has narrow, arching leaves

ending in frilly, white filifers, the sides dressed with pale, backward facing spines. To 4-6 ft, a standout in the

sunny, well-drained garden with only occasional summer water. Summer flowers are greenish white on dramatic

stalks to 12 ft. Frost hardy in USDA zone 7.

Dasylirion berlandieri

Northern Mexican collection, now about 4 years old, from plants rather similar in appearance to D. wheeleri but of

deeper blue and a more compact form. Extra filaments at the ends of the leaves make a dazzlingly golden halo

when backlit. Not too fussy about water but provide good drainage and good air circulation especially in winter.

Hardy to at least 10º to 15ºF; colder with good drainage.

Dasylirion berlandieri ‘Zaragosa Blue Twister’

Large sotal with 3 foot trunk and long spined blue-glaucous leaves that are twisted. Spines translucent when

backlit. Full sun, perfect drainage. A little summer water. Good in container, too. Frost hardy in USDA zone 7.

Dasylirion quadrangulatum

To us, the most dazzling of the Dasylirions, most resembling the genus Xanthorrhoea, the grass trees of Australia.

Eventually forming short trunks -- but don't hold your breath -- the rosettes of up to 8 ft or more wide. The leaves,

usually less than 1/4" wide in a tiny triangle, can stretch up to 4 ft or more and are produced by the gazillions,

making for an extremely graceful and very symmetric form moving beautifully with the slightest breeze. In the

garden they should be placed in a sunny, well-drained area with additional summer water in dry climates. Fairly

limited in range in northeastern Mexico, these collections -- from, believe it or not, 1991 -- are from over 8,000 ft

in elevation and might prove hardier than those already in cultivation. So far, upper teens F have not been a

problem; we'll find out if they go lower. They make fabulous container plants; just give them enough room.

Dasylirion texanum

As the name would imply, this gem of a garden plant is native to west and southern Texas into Mexico and is one

of the hardiest of the lot. Deep green rosettes, with small backward pointing spines and attractive golden filifers at

the ends of the leaves, eventually form small trunks but are attractive as focal points or repeated rosettes in the

garden. As denizens of the southern Great Plains, they love a thunderstorm or two in the summer and don't mind

being dry in the winter, though they are tolerant of moisture. Sun to dappled shade, the main problem with dappled

shade being dead leaves, not fun to pull out of the center of the plant -- your arm could get stuck that way, as my

dad used to say about forbidden things. Reports tell us of frost tolerance up to -20, USDA zone 5. Wow! Also great

container plants.



Dasylirion wheeleri

The best known and one of the more spectacular of the genus, these trunk-forming denizens of southeast Arizona to

southern New Mexico and south into Sonora can grow as tall as 8 ft with 4-5 ft rosettes of very pretty gray-blue,

adorned with small golden teeth and threadlike filifers at the leaf ends. Beautiful when back lit. Not fussy about

water or soil though would rather not sit in winter wet. Great container specimens. These high elevation collections

from southeastern Arizona should be frost hardy into the 0º to 10ºF range, USDA zone 7, especially if in bright

light with good air circulation and very well-drained soil.

Dasylirion wheeleri RCH 321

The best known and one of the more spectacular of the genus, these trunk-forming denizens of southeast Arizona to

southern New Mexico and south into Sonora can grow as tall as 8 ft with 4-5 ft rosettes of very pretty gray-blue,

adorned with small golden teeth and threadlike filifers at the leaf ends. Beautiful when back lit. Not fussy about

water or soil though would rather not sit in winter wet. Great container specimens. These high elevation collections

from southeastern Arizona should be frost hardy into the 0º to 10ºF range, USDA zone 7, especially if in bright

light with good air circulation and very well-drained soil. These from Randall Hitchin.

Dasylirion wheeleri SBHMPS 6749

One of the most attractive of the genus, this represents our collection from Santa Cruz County, Arizona many years

ago in one of our favorite canyons, rich in all kinds of semiarid goodies. Plants eventually growing to 6-10 ft with

4 ft spread of most beautiful gray-blue leaves with gold spination and leaf tips. Lovely when back lit. This is a

mid elevation collection so we expect frost hardiness of about 10 to 15F, mid USDA zone 8, recovering from

lower.

Eryngium yuccafolium

A North American native sea holly with serrated, gray-green yucca-like foliage that forms a clump to about 2 ft.

Architectural flower spikes rise to about 20" in summer and are held until the first hard frost. Full to part sun with

rich, well-drained soil. Long-lived and easy. Hardy to -20F - USDA zone 5.

Hesperaloe campanulatus [Mamulique Pass]TB3M 090799One of the larger of the false Yuccas from cental NE Mexico with leaves of deep green dusted blue and fanciful

filifers on the leaf margins. Flower spikes to 6-8 ft or more with the generally anything goes adaption of pinkish

open flowers in late spring to late summer depending on elevation and temperature. Hardy to at least upper zone 8

and has proven hardy in gardens in the upper end of zone 7. Good drainage. Bright light.

Hesperaloe chiapsii

A new species described by Greg Star, striking in silhouette and good for use as pot specimen or garden subject. It

is possible the least frost hardy Hesperaloe, receiving some leaf damage below 20F but worth the effort to protect

it. Full sun and some summer water for fastest growth.



Hesperaloe funifera

Surviving in unwatered street medians in Tucson, this ‘“ed” yucca is one tough cookie. Matures to 5 ft tall, upright

with a dozen offsets. Creamy white flowers on 8' stalks all summer. Full sun. No water. Cold hardy to 5F - mid

USDA zone 7.

Hesperaloe funifera x parviflora

Stunning evergreen perennial originally from Mt. States Nursery’s hybridizing, this with more of the size and

vigor of H. funifera, the leaves reaching 6 ft, and the lovely peach to coral flower tones and purpling leaves of H.

parviflora. Flower stalks rise to 6 ft +, flowering all summer Ohh! Bright light brings out leaf color. Frost hardy

into USDA zone 6. Easy to grow with good drainage.

Hesperaloe nocturna

Dense clumps of grass-like leaves to 5'. Upright night blooming white fragrant flowers on 10'+ stalks in summer.

Evergreen and suited for an abusive situation. No summer irrigation required.. 5F.

Hesperaloe nocturna ssp. nocturna

A most striking woody lily from northeast Mexico with clusters of upright leaves, to 4' or more, dark green with

silky white netting of hairs especially toward the rosette center. Flowers ons spikes to 10'.with small cream

trumpets just perfect for the local moths. Very architectural. Great container specimen. Summer water on

occasion. Full Sun for best hairiness. 10F

Hesperaloe parviflora

Extremely frost hardy succulent. Dense clumps of leathery, deeply grooved, blue-green leaves, to 3 ft tall and

spreading slowly to 5 ft wide, with upright blooming, salmon-pink, fragrant flowers on 10 ft + stalks in late

summer. Great for hummingbirds! Evergreen and suited for a difficult situation in sun (or light shade in hottest

climates) with no summer irrigation. Frost hardy to -20F, USDA zone 5.

Hesperaloe parviflora 'Color Hunt'

Blue leaved flowering yucca, 18-20” clumps of blue-green leaves covered with curling white filifers and flowering

stalks up to 5-6 ft with coral-orange flowers -- attractive to hummingbirds. Hardy to 0F or below -- some say low

as -20F. Good drainage; full sun.

Hesperaloe parviflora - weeping inflorescence

These seedlings from a vigorous plant selected by George Hull of Mountain States Nursery have blue-green

leaves,, to 3-4 ft and 7 ft inflorescences with warm coral-orange flowers on weeping branchlets. Quite possibly a

hybrid, this is a vigorous and...like...way attractive plant. In Phoenix, where it was selected, it seems particularly

prevalent around strip malls.... Otherwise it looks good in a container or any other garden spot with bright light and

occasional summer water for strong growth. Frost hardy in USDA zone 6.



Hesperaloe parviflora x funifera

Stunning evergreen perennial originally from Mt. States Nursery’s hybridizing, these show the lovely peach to

coral flowers tones of H. parviflora but with the size and vigor of H. funifera. The leaves of this Yucca relative can

reach 3 ft or more with flower stalks rising to 6 ft or greater and flowering an entire summer season. Ohh! Frost

hardy into USDA zone 6. With bright light good purple coloration can occur on the leaves. Good drainage.

Otherwise very easy to grow.

Hesperaloe parviflora - yellow flowered

A selection from Ron Gass at Mountain States Nursery in Glendale, Arizona, this form is typical of H. parviflora in

its 3-4 ft rosettes and 5-6 ft flower stalks but with canary yellow flowers. A very pretty and unusual selection and

most attractive when combined in single plantings with the coral-orange flowered forms. Full sun to part shade

with little summer water. An easy grower, frost hardy in USDA zone 6.

Manfreda ‘Macho Mocha’

Possibly a hybrid between Manfreda jaliscana and Agave scabra, this nearly 2' plant from the semi-desert canyons

just over the mountains from Monterey, Mexico, boasts deep purple leaves with, indeed, coffee-colored polka dots

over the entire plant. For sun, good drainage, and average summer water. Evergreen to 20F and root hardy into the

low teens, USDA zone 8.

Manfreda maculosa

Fleshy leaved Agavaceae from southern Texas & the mountains of Northern Mexico. Hardy in the ground in

USDA zone 8. Low spotted foliage with remarkable, 4 ft ft tall flowering stalks and fragrant, greenish pink, spring

flowers. Best in a bit of shade with summer water. Excels in a container where its leaves are best displayed. Protect

from ambitious slugs. Frost hardy in USDA zone 7.

Manfreda maculosa x M. virginiana ‘Spot’

A Cistus introduction, this hybrid of the most northerly of the agave clan grows to roughly 18” across slowly

clumping with leaves dusted blue adorned with deep purple polkadots. Evergreen to 20F; hardy to well below 0F.

The yearly flower spikes are more curious than beautiful. Some summer water; bright light to dappled shade.

Nolina bigelovii

Native to the US southwest and into northern Baja California and growing up to 6 ft tall and as wide developing a

trunk over time that can reach 10 ft tall. Leaves are grass-like, up to 3 ft long with filaments in the leaf margins.

Very drought tolerant needling little summer water once established. For sun and well-drained soil. Frost hardy in

USDA zone 8.



Nolina 'La Siberica' D07-64

A Cistus introduction from seed collected at 8000 ft, in La Siberica, Mexico, forming a symmetrical whorl of long,

graceful leaves. A handsome plant, eventually developing a nice trunk up to 6 ft tall. Best in sun with little summer

water. Frost hardy to 0F, USDA zone 7.

Nolina microcarpa

Smallish clumping sotol. Three foot long narrow leaves form a dense evergreen mound. White flowers held well

above foliage in summer. Full sun, a little summer water. Good drainage.

Nolina microcarpa SBH 6726

Beautiful, tufted, liliaceous perennial to 4 to 5 ft high and wide and retaining its dark green luster throughout the

winter. The leaf tips are edged in a curled “doodad,” making them even more interesting when backlit. This

collection from one of my favorite places -- above Jerome, Arizona at over 8,000 ft. The hardiness should allow

cultivation in areas of cold at the lower edges of USDA zone 5, possibly much colder with snow cover. The

inflorescences are narrow, reaching 8 ft or more. with clusters of small white flowers looking vaguely pampas

grassy. Drought tolerant though faster growing with regular summer water.

Nolina nelsonii

Like Gert Boyle of Columbia Sportswear, this is one tough mother. Hardy and thrives in Portland’s summers and

winters given a bit of summer water and excellent drainage. Single stemmed foliage plant until a decade passes and

15’ white flower stalks stun you. <10F.

Nolina texana

A bigger, bolder version of the somewhat more common and varied N. microcarpa. This Texas native grows to a

bold textured 5 ft with deep green arching leaves and creamy white flower spikes rising to 8 ft or more in spring

and summer. Exceedingly drought tolerant but a little summer water would increase its growth rate. Sun to dappled

shade. Hardy to about 0F, USDA zone 7, or even a little below.

Podocarpus chinensis [Yucca Do]

Though the name is somewhat questionable, the plant is certainly not. Given to us by Yucca Do Nursery some

years ago, this Podocarp spends several years as a delightful conical shrub with narrow, spring green foliage of

about 1” in length; we are told it can eventually grow into a large tree of 30’ or more. So far this gem has

withstood temperatures into the upper single digits Fahrenheit with no visible damage. We find it, however, thirsty

for some summer water in our part of the world.



Yucca aloifolia

One of the larger hardy Yucca, forming a trunk to 5-20 ft.... eventually. A great addition to the garden and fine in a

container as well -- easy in both. Leaves are large, to 2 ft, sweeping, and sharply pointed. Mature plants produce

spikes of white flowers tinged purple appear in early to mid summer. Full sun to half sun in well-drained soil. Easy.

Frost hardy to 0F, USDA zone 7.

Yucca aloifolia - red form

One of the larger hardy Yucca, a great addition to the garden, this strain with prominent red coloration. Great in a

container as well (quite hardy either way). Single trunked with large sweeping leaves. Full sun to half sun. Easy.

Yucca aloifolia ‘Variegata’

A long coveted form of this sharp-pointed, spectacular tree yucca, native of the deep Southeast, the variegated

forms have long been pass-around only plants because of their difficulty in reproduction. Now there's enough for

everyone! 3 ft wide, stacked rosettes on branched trunks -- to 5-8 ft and more -- the creamy white variegations,

tinting rosy pink in cold weather, make the plant's outline visible from quite a distance. Full sun to dappled shade

providing leaves do not gather in the rosettes and cause rot. Well-drained soil. Supplemental water in dry summer

places. Frost hardy in USDA zone 7.

Yucca baccata

This trunk-forming yucca is a knockout in the landscape. Curving trunks (to 10 per plant) snake out and stand up to

8 ft tall. Stiff filifered leaves. Short flowering stalks with loads of white flowers. Full sun, excellent drainage.

Architectural! Cold hardy to -20F, USDA zone 5.

Yucca ‘Bright Star’ PPAF/COPF

This mutant, an offspring of Y. gloriosa 'Variegata', has olive green and delightful, warm cream leaves, their

variegation covering most of the leaf. Not as fast growing as its parent, but vigorous nonetheless. To about 18” ,

enjoying partial shade to full sun….mostly shade in extremely hot summer climates. A definite bright spot in the

garden or in container, it has been unfazed by temperatures of 14F and will probably go to about 10F, the bottom of

USDA zone 8. Drought tolerant as with most yuccas but would enjoy occasional summer water to speed growth.

Yucca campestris

Mostly trunk-less species endemic to the plains of the Texas panhandle. Short dense ivory flower spikes rise out of

gray-green rosettes. Drainage is a must for hardiness in in USDA zone 7.

Yucca carnerosana

Large single-trunk forming yucca often up to 10 feet tall with 3-5 ft diameter ring of stiff leaves. Flowering stalk

short holding numerous greenish white fragrant flowers. Full sun. Frost hardy to 0F, USDA zone 7, or less.



Yucca carnerosana [Mexican Collection]

South Neuvo Leon (Mexico) collection of this widespread tree yucca. To 10 ft or more in the garden with thick

trunk and rigid leaves, to over 18", graced with curling white hairs along the margins and, in this form, a thick

ivory colored edge that make the leaves look particularly striking. 5-10F, mid to upper USDA zone 7, possibly

colder with protection. Full sun to only light dappled shade. Some summer water.

Yucca elata - large form SBHMPS 6733

As close to ‘It’ from the Addams Family as you can find in nature. Single trunked/multi-branched 10 ft+ tall yucca

with long hanging leaves and gobs of tall white flowering stalks. Sun. Cold hardy to -10F, USDA zone 6, or lower.

Yucca elata SBH 6720

Our collection of a particularly large form of this thread-bearing tree yucca. "Mom", in her native haunts of

northwestern Arizona, was nearly 15' tall with a dozen or so branches beautifully topped with 4', thin-leaved

rosettes cob webbed in white silk. One of the only North American filifered yuccas to form a trunk. Thrives in

most situations from severe drought to average garden water if provided good drainage and some supplemental

water where summers are completely dry. Lower end of USDA zone 7, possibly 6.

Yucca elephantipes ‘Silver Star’

Giant, trunk-forming yucca, to 20 ft or more, grown primarily for its glossy green leaves edged in white. Winter

flowers, creamy on tall spikes, are a bonus. For sun to mostly shade with average to occasional water. Frost hardy

only to the mid 20s F - mid USDA zone 9, so best as a container plants or houseplant with regular water.

Yucca endlichiana

Rare and beautiful small species from northern Sonora. Each leaf remains under 6" and is a quite succulent, deep

blue mottled purple. The plants form large caudices making them great for bonsai. But possibly the most intriguing

feature is their beetle pollinated flowers that are maroon-black and hang to rest on the ground near the plant. Fullest

sun. USDA zone 8 if drainage is excellent, possibly with protection from winter wet.

Yucca faxoniana

It has been long thought that many of the tree yuccas of northern Mexico are not frost hardy, but recently many of

us rosette-fanciers have discovered their toughness. Y. faxoniana produces 3-4 ft rosettes of stiff, emerald-green

leaves with symmetric, pearly cream to brown filifers adorning each leaf. Quick to form full sized rosettes, slow to

build a trunk, eventually to 16 ft or more, and slow to branch. Fastest when given plenty of root room, free draining

soil, and some supplemental water in very dry summer places. Excellent container plants. Prefer bright light.

USDA zone 7 with some success in warm zone 6 with excellent drainage and protection from freezing winds.



Yucca filamentosa

A fairly common yucca, especially in our older Portland neighborhoods. Handsome and easy. Trunkless, and

clumping, with stiff, evergreen leaves, to 2.5 ft. Thin filiments that shred from the leaf margins and interest and

texture. White flowers appear in summer on 3 to 6 ft woody stalks. Sun with some summer water. USDA zone 5.

Yucca filamentosa ‘Bright Edge’

Long lax foliage on this slowly spreading yucca. Excellent as a visual accent. The leaf edges aren’t sharp, so it can

line a path or border. Normal water and full sun for best color. Definitely frost hardy in USDA zone 7 and

reportedly in USDA zone 5.

Yucca filamentosa ‘Color Guard’

Amazing, variegated yucca, clumping to 3 ft, with gold-centered green leaves, the gold brightening in summer’s

light. And, true to the species name, the foliage is dressed up with curly white filaments. White flowers in spring

on 6 ft stalks. Sun, well-drained soil, and occasional deep summer water. Frost hardy in USDA zone 5.

Yucca filamentosa ‘Hairy’

Dazzling form of this southeastern native selected at the JC Raulston Arboretum in the early 1990s and just now

becoming available. 3 ft, trunkless rosettes of soft-textured but wide, blue tinted leaves are adorned with

particularly large numbers of curly white threads, giving the entire plant a dazzling cobweb effect. Wonderful

placed where backlighting occurs. One of the easiest to grow species in any soil, with bright light to dappled shade.

Frost hardy in USDA zone 4.

Yucca filifera

Tree forming yucca to upwards of 15 ft evemtually with 2 ft rosettes of tightly held blue-green leaves covered with

delicately intertwining filifers. Full sun. Cold hardy into the mid teens, mid-USDA zone 8; colder if very well

drained.

Yucca filifera ‘Golden Sword’

This very hardy yucca’s foliage is stunning, especially when the plant is more mature & becomes 6 or 8' tall with

multiple trunks. Tight stiff leaves always. Huge thrusts of white scented summer flowers. Full sun, a little summer

water.



Yucca flaccida 'Garland's Gold'

This southeastern native yucca, from clearings and sandy spots, is used to high rainfall and frozen ground in winter

so remains one of the most cold hardy species. The small clumps of under 2' have gently recurved leaves with

blue-green tint and small threads along their margins. Y f. 'Garland's Gold' has generous deep yellow margins

taking up over 1/2 the leaf surface, yet the plant remains vigorous. Striking for use as a focal point or hardy

container plant. Full sun to dappled shade; would prefer decent drainage and a bit of summer irrigation where dry.

USDA zone 4.

Yucca glauca - blue leaved form

Spiky tough evergreen yucca with bluish leaves and huge trusses of white flowers in summer. Full sun, not too

much summer water. Excellent in containers or as accents. Maybe in your parking strip.

Yucca gloriosa ‘Tricolor’

One of the most useful of the trunk-forming, southeastern US native yuccas found growing from South Carolina all

the way around to the Gulf side often within sea spray. 2-3 ft rosettes of upwardly pointed leaves and trunks as

high as 4 ft, this form variegated with cream and light yellow and infused with pinks especially with winter frost.

Tolerant and even fond of average garden water and very long lived in container. Very good focal point for the

garden. Has been quite happy into mid USDA zone 7.

Yucca harrimaniae

Able to easily thrive through the harsh winters of Denver, this small yucca has a handsome brown marginal stripe

from which white filaments emerge (think thuggy men in fringed leather jackets...). Short blue-green flowers. Sun.

Cold hardy to -20F - USDA zone 5.

Yucca linearifolia

One of the most beautiful yucca species, related to Y. rostrata. The 3 ft rosettes atop an eventual 3-8' trunk

resemble the Australian grass trees, Xanthrroea, or a dim version of Dasylirion quadrangularis. Flattened

somewhat triangular leaves of spring green to nearly turquoise and white flowers to 3' or so above the rosette.

From only a few scattered localities, these from north of Galleana, NL, Mexico, in a most diverse habitat. Its

southern habitat would indicate lack of frost toleranance but has so far withstood 5F. Ottherwise full sun to partial

shade. summer water with, as always, well-drained soil.



Yucca linearifolia 'Dusky Blue'

One of the most beautiful yucca species, related to Y. rostrata. The 3' rosettes atop an eventual 3-8' trunk resemble

the Australian grass trees, Xanthorrhoea, or a dim version of Dasylirion quadrangularis. Flattened somewhat

triangular leaves of spring green to nearly turquoise and white flowers to 3' or so above the rosette. From only a

few scattered localities, these from north of Galleana, NL, Mexico, in a most diverse habitat. This form is

particularly blue and quite vigorous adding 6-8" of trunk each year. Our plant often elicits comments from garden

visitors. The southern habitat of the species would indicate lack of frost tolerance but plants have so far withstood

5F. Full sun to partial shade and summer water with, as always, well-drained soil.

Yucca nana

Exquisite and tiny yucca from the San Rafael Swell of southern Utah. The 6-8" rosettes, with their undulate,

glaucous blue leaves edged white, seem as if a bunch of blue star fish were playing leap frog. Slowly multiplying

to form a small colony. Spectacular in garden or in pots: we have placed ours in a stone wall. Would love bright

light and free draining soil, preferably high in mineral content, but, really, not very fussy. Small 2-3 ft spikes of

pearly white flowers appear on mature plants in May and June. USDA zone 4, if not 3.

Yucca nana - prolific blue

A Cistus introduction. Of the many seedlings we’ve grown of this wonderful species from southern Utah, this

clone produced a lovely blue leaf, a pleasing green with age, and wonderfully symmetric filifers making it look

very much like a dwarf Agave. Clumping but with each rosettes measuring less than 6” in diameter. Perfect for

rock garden or container. We suggest not under-potting as Yuccas, even desert ones, enjoy moisture in the soil and

a generous root run. Frost hardy in USDA zone 4 or 5.

Yucca pallida

Native from Waco, Texas south, this clay-tolerant yucca has no trunk, but offsets rather nicely forming an evenly

spaced ‘grove’. Translucent leaf edges on glaucous blue, long leaves are an excellent late afternoon cheap thrill.

Each clump 2 ft tall and wide. Best where it receives a bit of water in the summer. Blooms best after a fire. Cold

hardy to 0F, USDA zone 7.

Yucca periculosa

From dry areas of southern Mexico, a trunk forming yucca to about 4 ft tall. Stiff, blue-green leaves make an

architectural statement in the well-drained garden. Frost hardy into the low teens, USDA zone 8.



Yucca recurvifolia

Large scale species, native to coastal areas of the Southeast and often used in Victorian days in our Portland

neighborhoods and elsewhere in warmer parts of the country. Pretty much no-fuss plants and one of the boldest

species for colder climates if provided reasonable water in summer in drier places. Each plant can grow from 4-5 ft

with 3" wide, weeping leaves of glossy green tinted blue and 4 ft spikes of white flowers, most often in June but

possible year round. As the plants form small trunks, some offsetting or branching occurs. Spectacular in

containers or in the ground. Reliable in USDA 7; has found success in zone 6.

Yucca recurvifolia ‘Gold Ribbons’

A Cistus introduction. This large growing native, from the Carolinas to the Gulf in sandy spots, forms a stunning

rosette of weeping leaves and eventually a trunk to 4-5 ft. The plant is useful in all forms but Y. r. ''Gold Ribbons',

can serve as a striking focal point or container plant with its blue dusted leaves and wide center strip of deep

creamy yellow. We have used it as a substitute for the more spectacular, gold variegated, New Zealand flax

(Phormium) in exposed or particularly frosty areas. Did we say spectacular? Fairly dry to quite damp conditions;

decent drainage a plus. Full sun to dappled shade. Not advisable to let too many leaves collect in the crown if in

shade. USDA zone 7; 6 in protected spots.

Yucca recurvifolia ‘Margaritaville’

Fabulous yucca, evergreen with soft foliage, variegated in creamy yellow striped green with green edges. Very

showy. Slow growing, to 4 ft x 6 ft eventually. Tall spikes of ivory bells in summer. Best in full sun to part shade

with occasional summer water for best appearance. Frost hardy in USDA zone 7.

Yucca recurvifolia ‘Marginata’

Soft leaves on this large, handsome yucca are green-centered and yellow-edged, 3 to 4 ft and arching from a 3 ft+

trunk. Large trusses of open white flowers in summer. Extremely useful in a container, but happy in the garden as

well. Full sun is best. Drought tolerant but appreciates occasional summer water. Cold hardy in USDA zone 6b.

Yucca recurvifolia 'Variegata'

Yellow-centered, green edged form of this large handsome yucca. 3-4 ft leaves arch from 3 ft+ trunk. Large trusses

of open white flowers in summer. Extremely useful in a container, but happy in the garden as well. Full sun is best

with occasional summer water until established. Frost hardy in USDA zones 8-11.

Yucca rigida

Bold textured relative of the stunningly gorgeous Yucca rostrata, spending its very long youth as a 2 to 3 ft rosette

of 1"wide, silver-blue leaves, eventually forming trunks to 5 to even 8 ft with small candelabras of white flowers in

summer at maturity. This species from northern Mexico requires full sun to dappled shade in the most deserty areas

and a touch of additional water in the driest spots. Not particular about soil as long as its not sitting in water. Our

plants are putting on about 6" of trunk each season. Warm USDA zone 7.



Yucca rostrata

Probably the most handsome of the hardy yuccas for the Pacific Northwest. Stiff grey-blue leaves form a halo

around a slowly elongating trunk. Full sun and well-drained soil for a happy plant. A little summer water for faster

growth. Frost hardy in USDA zone 7.

Yucca rostrata [Big Bend, Texas collection]


around a slowly elongating trunk. Full sun and well-drained soil for a happy plant. A little summer water for

faster growth. Frost hardy in USDA zone 6 with good drainage.

Yucca rostrata [Black Gap, TX collection]

From the Big Bend region of Texas this colony, forming the northernmost habitat for the species and the only one

in the United States, gives a beautiful cast to the entire landscape. Growing to over 10-12 ft, occasionally

branching into small trees with 4-5 ft rosettes, they are truly a stunning creature and a perennial in my top 10

favorite plants. That says a lot! Ours are seed grown and beautiful as garden or pot specimen with many hundreds

of leaves in each, rustling like grass off a thickened trunk…but wait, there’s more! As an already frost hardy yucca,

this is a northern colony, plants of which have survived in USDA zone 5, making it one of the two frost hardiest

tree yuccas.

Yucca rostrata [Mamulique Pass form]


around a slowly elongating trunk. Full sun and well-drained soil for a happy plant. A little summer water for faster

growth.

Yucca rostrata ‘Sapphire Skies’

A Cistus introduction. Although Yucca rostrata is one of the most gorgeous species available, and definitely one of

our top 500 favorite plants, it is exceedingly slow to reproduce from offsets, seed is difficult to come by, and

seedlings vary as to their...blue-osity. Yucca rostrata 'Sapphire Skies' is a selection from one of our collections in

the early 90s in northern Mexico, out of a seed batch of stunning blue-leaved plants. Through the magic of tissue

culture, we now have a reliable source. These vigorous young plants quickly form a 3 ft, multi-leaved rosette of

nearly jade-blue, forming 3 to 4 ft plants in 7 or 8 years under good conditions, eventually to 10 ft or more.

Excellent container plants, providing fine architecture, or repeated in the dry garden and looking of dusty blue

fireworks from a distance. Particularly beautiful reflected in late afternoon/evening light. Full sun to dappled shade.

Not particular about soil, excepting standing water. Some supplemental irrigation in dry summer places. USDA

zone 7; has been successful in zones 5 and 6 including the Denver Botanic Garden (Really!).



Yucca rostrata - specimen

These lovely creatures were grown from seed (NOT wild collected!). Many of these over 20 years old and hand

selected for form and blue color. They have been potted this year and might or might not have begun producing

this season’s roots -- if not, no fear, they will soon. All enjoy bright light with decent air circulation and all but the

most swampy of garden conditions - so very easy care. Frost hardy to USDA zone 6 and have even resisted lower

temperatures than that, but don’t push it. Water occasionally in summer west of the Sierra Cascades.

Yucca rostrata var. lineatus

Fabulous narrow leaved relation of the somewhat more common blue beaked yucca. This Mexican native grows to

about 4 ft with dazzling spring green of the narrowist leaves. Full to part sun; good drainage with summer water

foor faster growth. Not tested below 15F, but should be hardy to 0F or less - USDA zone 7 or below.

Yucca rupicola

This large textured species form the Texas hill country consists of slowly clumping, 1 to 2" wide, undulant leaves

of deepest green. Particularly striking when planted with silver-blues such as Festuccas or other blue tinted,

rosette-forming plants. An easy care creature if provided well-drained soil, supplemental summer water in

exceedingly dry places, and bright light, though at home in dappled shade if leaves do not collect in its crown.

USDA zone 6.

Yucca schottii

Single trunked yucca of the Southwestern New Mexico mountains, this very hardy species is excellent in the

garden. Tall and narrow with 3 ft long lax leaves. Tall white flowering stalks. Wicked sharp spine. Sun. Frost

hardy to -10F - USDA zone 6..

Yucca smalliana ‘Maxima’

Known by some as the little big Yucca. handsome upright rosettes dusted in blue to 3 ft. Flower scapes can

measure over 6’ & are adorned with large white flowers; usually in summer but anytime of the year in Portland.

Seems to set seed without Yucca moths hanging around. Almost any garden conditions with good sun and regular

water. Hardy to at least -30F - USDA zone 4.

Yucca tehuacana

A most handsome trunk-forming yucca from the Mexican state of the same name, to an eventual 8 to 10 ft -- yes

more, but none of us will live that long. Narrow, blue-green leaves in abundance make a beautiful and most

architectural rosette even before lift-off. Flowers are white tinted rose-pink on slightly leaning towers. Sun, lean

soil, and some summer water to boost growth. Frost hardy to 10 to 15 F – low to mid USDA zone 8 -- if winter

dry, otherwise protect below 15F. Fabulous container plant.



Yucca thompsoniana

This tree-like yucca is so happy in the Portland garden, it’s the first thing we planted when we arrived at our new

house. Ten years later, it’s head high and its soft leaves make passersby lovingly pet it. Full sun with good drainage

and some summer water. Related to and sometimes overlapping with Yucca rostrata, somewhat shorter and more

branched, occuring much further north in Texas with a great amount of cold. Frost hardy to -30F, USDA zone 4 or

even lower.

Yucca torreyi

Picturesque, very large Yucca with leaves in excess of 4 ft, eventually forming a small tree, usually single trunked,

to 10 ft. Native from SW Texas to the mountains of Cochua, Nuevo Leon, this represent a particularly blue leaved

form from south of the border. 0 to 10F, USDA zone 7; faster with some summer water. Full sun & good

drainage.

Yucca treculeana

Tall yucca, its trunk reaching to 12 ft with stiff bayonet shaped leaves, to 2” wide and 3 ft, long arranged evenly

around the thick trunk. Spectacular by itself but when it grows up, in say 4 to 5 years, a giant flower stalk appears

adorned with white flowers. Stunning! Originating in the US SW and Mexico, these are frost hardy to USDA zone

7.

Yucca whipplei [Santa Lucia Mountains]

Extremely stiff leaved yucca, these from wild collected seed from the Santa Lucia Mountains. Excellent drainage &

full sun are keys to success. 8 ft flowers stalks with dangling white fragrant blooms.
