Coltsfoot (Petasites frigidus) in a native plant garden
Salal (Gaulthera shallon) and fern
Cup fungus on a small decaying branch
Snowberry (Symphoricarpus albus) and bumble bee
Large leaves of Darmera peltata
Trillium ovatum
Asarum –wild ginger
Inside-out-flower (Vancouveria hexandra)
Western spirea, Spiraea douglasii
Water and chemical savings
Plants are adapted to climate and soils
Fewer pests and diseases
Observe and feed pollinators and other
wildlife
Native plants are not invasive in their
native area
What do you

Oxalis oregana (wood sorrel) and
Tolmiea menziesii (piggy-back plant)

Veratrum – false hellebore
Darmera peltatum
Public Library - McMinnville
Ribes sanguineum, Red
Flowering Currant
Roadside – Cathlamet, WA
California poppy
Sedum spathulifolium (center)
Lewisia cotyledon (bottom left)
Sword fern (Polystichum munitum)
Wild camas often grows in prairie-like settings amongst other plants
Note
contrasting
colors
Erythronium, trout lily, in a wild setting growing in drifts among mosses
Wild bleeding heart,
Dicentra formosa,
grows well in
masses as a
groundcover. Start
with plants spaced
about a foot apart
and let them fill in.
Early spring bloomers seem to ―glow‖ in a forest understory, but by summer,
they go dormant.
Contrasting colors
of native
penstemons and
daisies are also set
off by a nearby
stream. Let plants
intermingle, falling
into each other, to
get this effect.
Contrasting
colors can help
highlight each
individual plant
in a group
Indian paintbrush, a delphinium and cat’s ear
share the same small space
Lupines in masses in full sunlight show
off well
Masses of plants are
often spectacular, just
make sure that there is
other interest, such as
nice foliage, to add to
the garden setting, or
plant something else
that blooms in a
different season nearby
to shift interest there.
Right Plant-Right Place
Use complimentary or contrasting colors and textures
Go for Four Season color & interest
Use garden art, paths, or areas of ground cover, to suit your taste
Deer fern and moss
Our native camas in
nature is a seasonal
wetland species
In the garden, it
require sun or part-
shade and dry
summers
Camassia sp.
A good plant in the wrong
location will not thrive
This Pacific
Northwest species is
a great groundcover
To do best, however,
it requires ample
moisture, such as on
a wet bank
False lily of the valley, Maianthemum
dilitatum.
Oregon oaks are
beautiful but have
special requirements
Irrigation makes then
extremely susceptible
to root rot so dry
summers are a must
Oregon white oak, Quercus garryana
The native red twig
dogwood has many
features—flowers,
fruits, red bark, and
fall color
It can grow in many
garden locations and
exhibits drought
tolerance
Cornus sericea – red twig dogwood,
showing colorful leaves
The Western
serviceberry is a
large shrub
Attractive spring
flowers are followed
by bird-favored
berries
Western serviceberry,
Amelanchier alnifolia
Oregon iris (Iris tenax), Western columbine (Aquilegia canadensis), stream
violet (Viola glabella), and Western mockorange (Philodelphus lewesii)
Summer – An annual ―blue thimble flower‖ (Gilia capitata), Oregon sunshine
(Eriophyllum lanatum), Douglas aster (Aster subspicatus or Symphyotrichum
subspicatus ), and Columbia lily (Lilium columbianum)
Berries of salal (Gaulthera shallon) and blue elderberry (Sambucus mexicana).
Fall foliage of golden currant (Ribes aureum).
Berries of snowberry (Symphoricarpus albus) often last through the winter. Red
stems of Cornus sericea and evergreen foliage of sword fern (Polystichum
munitum) provide color interest
Contrast brings out
details
If you use blooms to
contrast, make sure
they bloom at the
same time
Yarrow (Achillea millefolium) and red
monkeyflower (Mimulus cardinalis)
White flowers
seem to
complement
those of other
colors
Make sure their
growing
conditions match
Nutka rose (Rosa nutkana) and Pacific
ninebark (Physocarpus capitatus)
An adaptable native
succulent is Sedum
spathulifolium
Offset it with rocks
or other materials
Spoon-leaf stonecrop, Sedum spathulifolium
Groundcovers
add interest
and often
intermingle well
with other
plants
Dunes strawberry, Fragaria chiloensis
Here a ground
cover, fern and tree
trunk add garden
interest
Look for opportunities
to use naturalistic
combinations
Groundcover is Pacific waterleaf,
Hydrophyllum tenuipes
Tree trunks
provide a
pleasing
backdrop for
many plants
March flowers of red flowering currant, Ribes
sanguineum, also attract hummingbirds
In this city park
planting, individual
plants are set in
spacing, with bark
mulch, all adding
visual appeal
Oregon iris (Iris tenax) and blue fescue
Osoberry, Oemleria
cerasiformis, is one
of the earliest shrubs
to bloom. Summer
berries add more
appeal.
Don’t overwater but supply what is needed for the plant to be successful in your garden
Establish carefully—trees and shrubs need extra water to establish
Let plants take their natural formLittle if any fertilizer to maintain natural
shape and sizeAmend soil only with organic matter—no
sand!
