he Royal Botanic Garden Edinburgh’s

popular adult education summer school

returns this year with an even wider range of

courses. Discover a new hobby or brush up on

long-forgotten skills, all while enjoying the

magnificent surroundings of the Garden.

New to the summer programme are two

exciting art courses presented by RBGE tutor

Jacqui Pestell:‘Loose style botanical watercolour

painting’ and ‘Silk painting’. “In the ‘Loose style’

course, we will explore the wonderful effects of

runny paint on Japanese mulberry paper.We’ll

use broad brushstrokes and paint washes in a

style that is much freer than traditional

botanical painting,” says Jacqui.“This is the style

I tend to paint in for my personal work, so I’m

looking forward to sharing this with others.

”The ‘Loose style’ course runs from

Tuesday 27 to Thursday 29 July.

Jacqui also presents a two-day silk painting

workshop on Saturday 3 and Sunday 4 July.“This

taster course is great fun, and all the more

rewarding because it results in something you

can wear like a scarf,” explains Jacqui.“We’ll use

bright colours and bold floral shapes to create a

unique design.”

If art is not for you, a number of horticulture

and botany courses offer opportunities to

broaden your knowledge and enjoyment of the

world of plants. Looking after your house plants

is rewarding, but sometimes tricky and

challenging, so RBGE experts are presenting two

morning sessions to share their tips.

‘Caring for exotic house plants’, presented by

horticulturists Bruce Robertson and Cath Evans,

looks at the tropical plants we keep in the

home, while a new workshop called ‘Plants for

your conservatory and home’ explores house

plants from temperate regions.“From stunning

climbers and pelargoniums to cacti to venus fly

traps, we’ll cover old favourites and some

unusual choices,” says Cath Evans.

Both sessions include a glimpse behind the

scenes at RBGE’s own collections of these plants.

The date to diarise for exotic house plants is

Saturday 26 June, while ‘Plants for your

conservatory and home’ takes place on

Saturday 28 August.

If you prefer to leave your houseplants

behind and head outside to get better

acquainted with Scotland’s native plantlife,

there are three day-long workshops on offer:

‘Wildflower identification’ (Saturday 26 June),

‘Lichen identification – a beginners’ guide’

(27 June) and ‘British tree identification’

(Saturday 10 July).

RBGE experts in each field, Phil Lusby, Chris

Ellis and Tom Gifford respectively, give practical

pointers for identifying species.The tree

identification session also includes a ‘Celtic

trees’ tour with Garden Guide Stephanie Ledger,

looking at the traditional uses, superstition and

ritual connected with native trees.

16 GET CREATING!Summer school for adults.

more than two centuries of

imagination and creative energy have

been invested in the buildings and

landscape of the Garden at Edinburgh.

Over 700,000 visitors take pleasure in

this beautiful place each year. Those

among them who know the world�s

finest botanical gardens cite three

factors which make this Garden pre-

eminent: the sheer diversity of the plant

collections, the quality with which they

are presented and the stunning backdrop

of Scotland�s capital city.

The Botanics can rightly be proud of

its high standing, but a reputation for

excellence demands constant care and

the commitment of significant resources.

We are fortunate that many people

share the vision of a bright future for the

Garden and are willing to invest in it.

With funding from the Scottish Arts

Council (SAC) we have recently

refurbished Inverleith House Gallery,

the Grade A listed building at the heart

of the Garden. Thanks to the Robertson

Trust, a second landmark building,

the Victorian Palm House, is

also undergoing a remarkable

transformation.

Both projects have benefited from

substantial funds from our principal

sponsors, the Scottish Executive

Environment and Rural Affairs

Department (SEERAD). Most recently

SEERAD has awarded even greater

capital funding, totalling over £5.6

million pounds over the next two years.

This will enable us to extend the

Herbarium building, where the results of

our global efforts to preserve a record of

the earth�s botanical diversity are housed.

The funding also provides the means

for a programme of maintenance to

improve the fabric of Inverleith,

Benmore, Logan and Dawyck, and to

meet the requirements of the Disability

Discrimination Act. We are immensely

grateful to Scottish Ministers, especially

Ross Finnie and Allan Wilson for this

investment. Their support, together with

that of our Members, Companions,

Patrons and a growing body of sponsors,

allows us to move ahead with our

ambitious plans for the future.

In the Edinburgh Garden, the Chinese

Hillside is being extended with new plant

introductions whilst plans for the

Gateway continue to take shape.

We are grateful for your interest and

support in these exciting times of

renewal and development.

Often called ‘the Galapagos of the Indian

Ocean’,the Soqotra Archipelago,off the

Horn of Africa,is home to over 300 unique

plants such as the bizarre dragon’s blood

tree,Dracaena cinnabari (above).For

centuries,the traditional culture of these

four desert isles,governed by Yemen,has

relied on plants to provide life’s essentials.

Visitors and staff alike are set to benefit from

a new £5.6 million pound programme of

capital investment in the infrastructure of the

National Botanic Gardens of Scotland.The

Garden’s funding body,the Scottish Executive

Environment and Rural Affairs Department

(SEERAD) recently announced that it has

allocated this sum over two

years to fund maintenance and

repairs at Edinburgh, Benmore,

Logan and Dawyck,and to make

modifications in line with the

Disability Discrimination Act.

A much-needed extension to

RBGE’s world-renowned

Herbarium building (right) will

also be built using this additional capital,

allowing for a 25 per cent expansion in

storage space for its scientifically important

collection of pressed plant specimens.The

two million strong collection,representing

plant life from around the world,grows at a

rate of 10,000 a year.

foreword

Capital boost for Garden’s infrastructure

A rare lichen last seen in

Edinburgh in 1797 has

made its reappearance in

the Edinburgh Garden.

RBGE’s lichenologists

Brian Coppins and Chris

Ellis were examining

lichens growing on plants

in the Azalea Lawn when

they discovered the

gristle lichen,Ramalina

fraxinea,attached to

a stem.

The gristle lichen has declined,sometimes

to local extinction,in many parts of Britain

due to high levels of sulphur dioxide air

pollution prevailing since the Industrial

Revolution.It is thought that rigorous and

effective measures to reduce air pollution in

the last decades have allowed lichens such as

this to return to areas where they had

previously died off.

The specimen found (left) consisted of

several rigid,strap-like lobes,the largest being

8cm long.Under ideal conditions,this lichen

can attain an impressive length of 30cm.

Cleaner air? Lichens don’t lie…

The Royal Botanic Garden Edinburgh is

renowned for the size and scope of its

Rhododendron collection.In April,RBGE staff

exhibited a selection of rhododendrons

from Edinburgh,Benmore and Dawyck

Botanic Gardens at the Borde Hill Camellia,

Rhododendron and Magnolia Festival.

They entered six plants in four competitive

classes of the RHS Rhododendron

Competition,which took place at

the Festival.

The result was a first prize,the McLaren

Challenge Cup,for a stunning Rhododendron

roxieanum specimen

(right),grown at

Dawyck.“ We chose to

exhibit this particular

specimen because it’s a

mature plant,from

material that could

well have been

collected in China by

the legendary plant

hunter George

Forrest,” says Dawyck

Curator David Knott.

RBGE’s other prize

winners were R.aff.magnificum from

Benmore,which took fourth prize in its

class,and R.adenogynum from Dawyck,

recipient of a third prize.

NE WS

Mary Mendum (née

Bates),1945 – 2004

In February,the Garden

lost a special colleague,

talented botanist and

illustrator Mary

Mendum. A zoologist by

training,Mary joined the

RBGE in 1987,working

with Paddy W oods on

revisions of orchids and

producing illustrations

for these.She was also

involved in Gesneriaceae research and

the genus Aeschynanthus became her

main interest.

Mary went on seven plant collecting

expeditions to Indonesia,Malaysia and

the Phillipines – these yielded a

number of new Aeschynanthus species,

which she was describing.She was also

a gifted botanical artist who had

paintings published in several

prestigious books and journals.

She is greatly missed her friends,and

by the wider community as the

capable artist,scientist and generous

person that she was.She leaves her

husband,John,and three children,

Neil,Tom and Jo.

“There are two theories about

how this happens,” explains Pete.

“The first is that the distribution of a

particular species was much wider in

ancient times, and that clusters of it

between the now vastly separated

populations have gone extinct for

some reason or other.

“The second theory is that the

species has managed to disperse

from its main range, giving rise to an

isolated colony thousands of miles

away.” As David Long expands,

either could be true for a liverwort

such as Anastrophyllum – liverworts

are among the most ancient land

plants, and over the ages their

distributions would change as the

earth’s climate changed. As for ultra-

long distance dispersal, this is a

theoretical possibility, since liverwort

spores are very light and hardy.

“The question of how a disjunct

population of a certain species here

in Scotland came about is a very

interesting and important one,” continues

David. “If we can answer this question, it

would help us understand the history of the

Scottish flora better, and its relationship to

the world’s other floras. It places our plants

in a global context and, for a particular

species, helps us decide the conservation

value of the Scottish population.”

Modern genetic science offers a means

of unravelling the mystery of how disjunct

populations came about. By determining

how much genetic variation there is

between disjunct populations of a particular

species, one can draw conclusions about

their origins. Pete Hollingsworth explains:

“If distributions are ancient, there should be

major genetic differences between

populations separated by thousands of

miles, as they would have accumulated

different mutations in their DNA. However,

if they are due to recent long-distance

dispersal, there will be very few differences

in their DNA.”

Markers provide a mapThe major four-year project ‘Microsatellites

as genetic markers’ is a collaboration

between the Royal Botanic Garden

Edinburgh (RBGE) and the Scottish Crop

Research Institute (SCRI).

“Using plants including Koenigia and

Anastrophyllum as case studies, the project is

assessing the usefulness of various genetic

techniques in biodiversity work,” says Pete

Hollingsworth. “Most modern national and

international conservation programmes

recognise genetic biodiversity as an integral

element of conservation,” he continues,

“yet there is no clear consensus on how to

measure it.”

So what exactly are Pete and his

colleagues investigating? “Different genetic

tools give one different insights,” he

explains. “Because the sequence of the

entire genome for a particular organism

takes years to determine, one simply

cannot compare entire genomes. Instead

genetic markers are used. This approach

samples genetic variation rather than

measuring entire genomes. A familiar

example of genetic markers being used

to determine differences is DNA profiling

in forensics.

“However, there are several ways of

obtaining genetic markers – for example

one can randomly sample a large number of

regions in the genome; or zoom in on a

small set that shows high levels of variation

from individual to individual.” These

different methods could possibly lead to

different conclusions about genetic

relationships between individual plants or

plant populations. So it’s a case of working

out which method supplies genetic

information most suited to various types of

biodiversity research.

he Iceland purslane, Koenigia

islandica, is a tiny annual with greenish

flowers. It occurs in the arctic and sub-

arctic regions of the northern

hemisphere, especially Iceland, Alaska and

the Faroe Islands. In Britain its only

footholds are on Skye and Mull, where

populations are rapidly declining – much to

the concern of conservationists.

It also grows thousands of miles away

on the other side of the planet, on the stark

and windswept island of Tierra del Fuego at

the extreme southern

tip of South America.

A leafy liverwort

called Anastrophyllum

joergensenii, or

Joergensen’s notchwort,

has an equally

remarkable distribution.

It is rare – in Scotland it

is classified as a Red Data Book species, and

is found on only a few hills in Wester Ross

and Sutherland. A small population grows

on a single mountain in Norway’s

Fjordlands. “However, its main stronghold is

the Sino-Himalaya, where populations

thrive in high mountains in Nepal, Bhutan

and China’s Yunnan Province,” says

RBGE bryologist David Long, who has

been collecting and studying it for a

number of years.

W orlds apart?“What’s fascinating about both

these species is the massive

distances between main

populations, with literally

thousands of miles dividing

them,” says RBGE scientist

Pete Hollingsworth, who is

leading a major research

project into disjunct populations. Koenigia

and Anastrophyllum are two of the subjects

of this study, which is using genetic tools to

investigate the phenomenon.

They may seem plain and insignificant, barely worth a second look. But two small native plant species – one a diminutive, flowering

annual and the other a liverwort – have inspired botanists to hunt for them in remote places. What makes these little plants

remarkable? Not their appearance, but their distribution… in isolated pockets at opposite ends of the earth. RBGE scientists tell Ida

Maspero how their investigations of these plants are pushing the boundaries of genetic science.

To the extreme

Disjunct populationsIndividuals of any particular plant species

are never distributed evenly across its range.

They live in clusters or populations,

physically separated by metres or miles.

When these distances are enormous, the

populations are said to be disjunct.

GenomeThe genome of a living thing refers to all

of its genetic material: its entire set of

chromosomes, containing all its genes

and DNA.

Biodiversity in context“The project also places Scottish

biodiversity in a global context,” adds

David Long. A better understanding of the

genetic relationships between Scottish

populations of rare plants, and populations

elsewhere in the world, could help set

conservation priorities.”

Whereas methods for measuring

habitat and species diversity for plant

conservation are well established, the

methods of gathering genetic data for this

purpose still need plenty of testing.

As genetic technology advances apace,

new techniques become more accessible

and easier to apply. It is hoped that, by the

time the Garden’s Microsatellites project

concludes early next year, it will have

cracked the code, so to speak, in providing

guidelines on which genetic techniques are

helpful to biodiversity studies, and under

what circumstances.

For botanists trained in the traditional

plant sciences such as taxonomy, working

with genetics provides “an exciting new

angle”, says David Long. “Traditionally we

have described the plantlife of, say,

Scotland. With genetics we can

look deeper and explain the origins

of a flora.”

Let’s return to the liverwort

Anastrophyllum, and what the study has

revealed so far. “It seems that the Scottish

population is remarkably similar genetically

to the Himalayan, so is likely to be a

relatively recent dispersal,” says David

Long. This surprising result indicates that

migration over thousands of miles is

possible. “However, early indications are

that the tiny Norwegian cluster is

genetically quite different from the Scottish

and Himalayan groups, maybe even distinct

enough to be considered a separate

species. So conserving it is crucial.”

Powerful partnershipsThe Microsatellite project has two main

threads: investigating disjunct populations,

and testing the use of genetic markers for

conservation. However, its significance

extends further, to building partnerships

for the future.

“By working with the Scottish Crop

Research Institute, we are transferring

technology,” explains Pete. “The SCRI is a

leader in the field of crop genetics, and by

forging links with them we are able to tap

into their expertise to apply sophisticated

gene technology to plant conservation. In

turn, colleagues at SCRI have access to our

expertise in population genetics and

biodiversity conservation.”

The project funds a post-doctoral

researcher at both partner institutes: Jane

Squirrell at RBGE and Mary Woodhead at

SCRI. “RBGE and the SCRI have

complementary strengths,” says Jane, who

researched microsatellites at the University

of Newcastle before coming to RBGE three

years ago. “Mary and I are in daily contact

and share all our data and observations.”

UK conservation bodies Scottish Natural

Heritage (SNH) and English Nature are

partners too, inasmuch as they are “end

users of the data,” says Pete. “The outcome

of this project will make a direct

contribution to these bodies’ practical

implementation of the UK Biodiversity

Action Plan (BAP). As Dr Chris Sydes,

Species Group Manager at SNH, stresses:

“The application of genetics in Scottish plant

conservation is a relatively recent

development, and it has great potential for

casting new light on the taxonomy,

reproduction and world importance of

particular plants. The genetic work being

done at the Botanics can help us answer

these key questions, and so help us plan how

best to conserve a species. So it has very

real and practical value.”

Traditionally plant science has focused on the

study of the structure of a plant. However

modern advances in genetics have given

botanists a whole new window on the plant

world, at a molecular (sub-cellular) level. RBGE

acquired facilities for molecular studies around

10 years ago. In recent years the demand for

genetic data has risen rapidly – and with it the

need for ever faster means of analysing DNA.

“The breadth and depth of this project in

particular is allowing us to step up the

technological pace of our research,” says

Pete Hollingsworth.

Recognising this increased

need for high-throughput

analyses, RBGE has recently

invested in two new

automated DNA

sequencers, which,

together, have doubled

the capacity of the

previous system, while

reducing preparation time

by 75 per cent.

A better understanding of

the genetic relationships

between Scottish

populations of rare plants,

and populations elsewhere

in the world, could help set

conservation priorities.

Field studies of disjunct populations have

taken Garden staff around the globe to places

of splendid isolation, breathtaking beauty,

harsh weather… and danger!

David Long has tramped the mountains of

the Himalaya, northern Scotland and Norway’s

Fjordland, hunting down the liverwort

Anastrophyllum joergensenii, which lives under

boulders and in rocky crevices in dwarf scrub

heathlands. In October 2001 his expedition in

eastern Nepal was cut short by a meeting with

armed Maoist rebels, forcing him to re-route to

central Nepal… where, thankfully, he was able

to track down the subject of his study.

Searching for the tiny Koenigia islandica in

Alaska’s Denali National Park in 2002, post-

doctoral researcher Jane Squirrell had a close

encounter of the creature kind.

“We took the tourist bus into the Park, to

take us to a valley where Koenigia had last been

collected in the 1950s. About two hours into

the ride, the bus driver slammed on brakes and

shouted ‘Bear!’ To the passengers’ delight, a

grizzly bear mother and cub were playing less

than 10 metres away.

“Suddenly we realised that this was the

very place where we were due to search! We

reluctantly got out the bus, cautiously eyeing

the grizzly and her cub, who seemed unaware

of our presence so nearby.We knew it’s unwise

to surprise a bear, so as we set off a

spontaneous chorus:‘Hey bear!’ resonated

through the valley.

“We soon developed a stop-start-search

strategy. Heads down, we strained our eyes for

K. islandica in the moss carpet, with frequent

stops to monitor the bears’ position. Finally

mother and cub left us, bounding up the

hillside.Towards the end of the day our

apprehensive search was rewarded –

we found our tiny quarry poking out from

the moss carpet.”

he Victorians loved

ferns for their

architecture – their

elegant structures,

delicate repetitive patterns

and their enormous variety.

The number of variations,

even within one species,

captured the Victorian

imagination and led to the

widespread fashion for

collecting and cultivating ferns.

For present-day fern

enthusiasts, developments in

molecular biology have added

another dimension to explore

this variation in species, and it

is this level that has fascinated

Dr Mary Gibby throughout

her career.

“My early work on ferns

stems from my interest in

plant chromosomes and what

they can tell us about the

evolution of species,” she

says. “In Victorian times,

people recognised the variety

within species, but when we

started looking at

chromosome numbers we

realised there are far more

species than we had imagined.

What were thought to be

varieties were found to have

totally different numbers of

chromosomes, and have since

proved to be distinct species.”

Mary’s interest in ferns

began as an undergraduate

student, inspired by the work

of the late Irene Manton,

Professor of Botany at Leeds

University, who had

undertaken seminal research

on fern genetics. She

developed this interest with

PhD research on the evolution of

Dryopteris, the buckler ferns, and later as a

researcher at the Natural History Museum,

London, continued studies on hybridisation

and speciation in the fern groups Asplenium,

Dryopteris and Polystichum. By the time she

came to RBGE in 2000, her focus was on

the conservation of ferns in the UK.

The complex issues involved in fern

conservation are illustrated by the example

of the Killarney fern, Trichomanes speciosum

– a very rare fern with delicate translucent

fronds, which thrives in deep shade and high

humidity. The Victorians collected it to near

extinction, growing it in enclosed glass

W ardian cases. Botanical surveys

have revealed only 10 remaining

populations in Britain.

The plant that we recognise as the fern is

actually the sporophyte generation (see

illustration), and the surveys were focused

on this. The gametophyte is composed of

tiny strands made of branching filaments of

cells, which look like the green felt of a pool

table. This had gone unnoticed until

botanists searching for similar ferns found

the gametophyte of the Killarney fern in

places where the sporophyte doesn’t grow.

The surveys expanded and now

gametophyte colonies have been recorded

from northern Scotland to the south coast

of England, and even in central Europe,

some 1,000km from the nearest

sporophyte. It is thought that they may

have survived there, persisting by slow

vegetative reproduction, since a warmer

period after the last glaciation 8,000

years ago.

“It’s like having a living spore bank out

there in the wild,” explains Mary. “If the

climate gets warmer and wetter, these

gametophytes could produce sporophytes

again.” This means the Killarney fern is not

an appropriate species for a reintroduction

programme. Instead, conservation efforts

are focused on habitat preservation.

RBGE’s four Gardens showcase the

diversity and beauty of ferns and fern allies.

Of the 15,000 known species worldwide,

the Garden has 6,000 herbarium specimens

and more than 300 species in cultivation,

including the world’s largest collection

of horsetails.

Propagating plants from fern spores is an

exacting job. In the Growing Room at

Edinburgh, horticulturist Andy Ensoll

ensures that the necessary warm, moist

conditions are maintained for the spores to

develop into gametophytes and then to

produce sporophytes. The plants are then

pricked out, allowing them room to

develop, and hardened offbefore being

planted out at whichever Garden offers the

most suitable climate.

InverleithIn the Glasshouses, the Fern House mimics

a warm, temperate rainforest. Ferns of

every shape and size are displayed here,

draped along the banks of the stream and

sprouting from the trunks of the huge tree

ferns, which spread their fronds right up to

the glass roof.

BenmoreNative ferns are in their element in

Benmore’s moist, oceanic climate. Species

such as the lady fern, buckler fern and

shuttlecock fern are widespread throughout

the wooded hillsides. As you enter the

Garden, the tall, leafy royal fern, Osmunda

regalis, can be seen from the bridge, and a

variety of ferns thrive around the pond. A

feasibility study is currently underway to

assess the viability of restoring the ruined

Victorian fernery.

LoganTree ferns are a prominent feature of

Logan’s exotic landscape, with over 100

specimens of the enormous Australian tree

fern Dicksonia antarctica – the tallest are

now more than four metres high and over

150 years old. The fern collection is

expanding with new species introduced last

year, including some which are very rare in

cultivation. New plantings of Cyathea dregei,

grown from material wild collected in the

Drakensberg mountains of South Africa,

have survived their first Scottish winter, and

Thyrsopteris elegans from Robinson Crusoe

Island (Fiji) is settling in beneath eucalyptus

trees in the Woodland Garden.

DawyckAmong Dawyck’s varied fern collection is

the sword fern, Polystichum munitum. Its

leathery leaflets and rugged nature are well

suited to Dawyck’s climate and it grows in

abundance. The Scottish Rare Plant Trail

features the tiny oblong woodsia, W oodsia

ilvensis, which was collected almost to

extinction in Victorian times and is now

very rare. Many Dryopteris species from

Dr Mary Gibby’s research collection have

been planted on the edge of Dawyck’s

cryptogamic sanctuary, and visitors can

‘spot the difference’, comparing the subtle

variations in these ferns – a challenge to the

untrained eye.

A fascination for ferns

As fern specialists from around

the world gather at RBGE for a

major conference this summer,

Dr Mary Gibby, the Garden’s

Director of Science, tells Anna

Levin about her fascination for

this ancient plant family.A temperate rainforest under glass in the Fern House, Edinburgh. PHOTO: DEBBIE WHITE

Inset:Dr Mary Gibby in the Temperate House with Dryopteris crispifolia, which is found

only in the Azores. As part of her PhD studies, Mary explained how it evolved from a

hybrid between D. aemula and D. azorica.

Like all ferns, the life cycle of

the Killarney fern is one of alternate

generations.

The sporophyte generation

produces spores which germinate to

give the filamentus gametophyte –

branching filaments of cells – and

the gammae, which allow the

gametophyte to spread vegetatively.

At the gametophyte stage,

‘swimmers’ from the male sex organ

fertilise the ‘egg’, and this develops

into a new sporophyte.

“Ferns are part of our heritage and we

want to maintain the breadth of that

heritage,” says Mary. “Only by studying an

individual rare species in detail can we

develop suitable plans for its conservation.

RBGE is an important centre for research

on Scotland’s threatened plants. By working

closely with conservations agencies such as

Scottish Natural Heritage (SNH), we are

helping conserve our native flora.”

nverleith House, designed by David

Henderson in 1774 as a family home for

wealthy agriculturist James Rocheid, has a

chequered yet distinguished past. In the

late 1870s it was partially destroyed by fire

and then became the official residence of

successive Regius Keepers. In 1959, Regius

Keeper Harold R. Fletcher relinquished his

residential privilege so that it could become

the founding home of the Scottish National

Gallery of Modern Art – Fletcher had

a rare passion for both art and

botanical science.

Between 1960 and 1984, this new

National Gallery drew visitors from home

and abroad to see its growing permanent

collection of modern and contemporary

art. Temporary exhibitions were also

staged, and sculptures by Moore,

Hepworth and Giacometti were displayed

outside in the Garden.

By 1984, the Gallery of Modern Art had

outgrown Inverleith House, forcing it to

move. In 1986 however, the House re-

opened with a programme of temporary

exhibitions run by RBGE itself, and 1990

saw a major refurbishment of what had

now become the Garden’s own gallery.

Since then, over 100 exhibitions have been

staged – a programme of international

status featuring a diversity of work, from

Rory McEwen, Pierre-Joseph Redouté and

Stella Ross-Craig, to Andy Goldsworthy,

Callum Innes and Carl Andre. Damien

Hirst’s sheep in formaldehyde even paid a

visit in 1994.

Last year, Inverleith House started

receiving annual core funding from the

Scottish Arts Council (SAC) to support its

programme; and was awarded a grant of

£150,000 from the SAC’s National Lottery

Funds for refurbishment.

Now, for the first time, visitors of all

ages and backgrounds have access to an

education space located in the basement.

An Arts Education Officer, funded part-

time by the SAC, will develop a unique

series of events to complement the

Garden’s schools, adult and community

education programmes. In addition,

wheelchair users now have easy access to

the entrance area, where there is a

cloakroom and a small bookshop. New

lighting has been installed throughout, and

there are improvements to the interior

finish, including the staircase.

On 7 August Inverleith House re-opens

with the first UK museum exhibition by the

Los Angeles-based artist Robert Therrien,

who explores the mind of childhood and

the realm of the domestic.

Since Inverleith House is now set to

fulfill, better than ever, its role as a

house for art. Surely Harold Fletcher

would have approved.

Clay in Bloom (7 August to 19 September) is

staged by the Scottish Potters’ Association

to celebrate its 30th anniversary. The

ceramic pieces on show, from the very

large and robust to the small and delicate,

demonstrate a natural affinity between

nature’s plant forms and the tactile medium

of clay.

The 18 exhibiting artists, who were

selected on a competitive basis, have each

taken the plant collections at one of the

National Botanic Gardens of Scotland as

their inspiration. The entire creative

process for each piece is revealed: from the

source idea, through the technicalities of

building, to the finished piece.

The range of styles on show reflects the

broad scope of ceramic practice in

Scotland, and the versatility of clay itself.

“By sharing the creative process we are

highlighting a variety of styles and

techniques,” says SPA chair Fiona Duckett.

Visitors have the chance to discover the

joys of clay for themselves at a series of

associated events called Hands On! Clay in

Bloom. Young visitors can get a feel for clay

at the hands-on area in the Hall. SPA artists

lead workshops and taster sessions for

adults throughout August, introducing

building and decorating techniques.

No experience is needed and the sessions

are drop-in. For details, see the Events

Programme or visit www.rbge.org.uk

Clay in Bloom is made possible by a grant

of £20,665 from the Scottish Arts Council

National Lottery Fund; and funding from

the Craft Pottery Charitable Trust.

oth are collective shows of

specially-made works by top

Scottish artists; and both draw

inspiration from the world of plants

and the dazzling variety of textures and

forms to be discovered within it.

Botanical Threads (8 July to 1 August) is

an exhibition of over 60 works, with an

emphasis on embroidery. It showcases the

talent of Group XII, a collective of 25

Scottish-based textile artists who use both

traditional and modern techniques in the

creation of their work.

Though the green kingdom provides the

theme for the exhibition, individual artists

have used innovative techniques in hand-

dyeing, weaving and the manipulation

of paper and plastics to create highly

original pieces.

As Annetta Floydd, spokesperson for

Group XII, states, textile

design and embroidery have

always had an established

place in history: “From the

Bayeux Tapestry to the work

of Kaffe Fassett, textile-based

art is just as important in

providing an insight into our

lives and our landscape as

more well-known media. It is

also enjoyable and

rewarding. We hope that this

exhibition will encourage

visitors to have a

go themselves.”

‘The paintingsI

In the early 19th century, Scottish doctor

Robert Wight travelled extensively

throughout southern India, working as

a plant taxonomist. With the help of

Indian collectors he assembled a vast

herbarium collection and described a

remarkable number of genera and species.

He also produced a renowned series of

illustrated books on the

southern

Indian flora.

His collections are now

widely scattered in major

herbaria, but one of the most

important – containing

23,000 specimens – is

housed at RBGE, having come with the

University of Glasgow’s herbarium in 1966. In

addition, 500 of the original paintings

commissioned for Wight’s books were tucked

away in the RBGE library’s extensive

illustrations archive. RBGE taxonomist

Henry Noltie came across these paintings in

the course of his work on the Indian flora,

and realised the rather crude black and white

reproductions in Wight’s books gave no hint

of the incredible quality of the original

watercolours by two Indian artists – Rungiah

and Govindoo.

In 2002, Henry embarked on an extensive

research project to conserve the paintings,

catalogue the corresponding herbarium

specimens and produce a book on the

paintings and Wight’s life and work in India.

“In many other collections of Indian

botanical drawings, the related herbarium

specimens have been lost,” he explains.“This

collection is so important because we have

both elements and because of the level of

scientific documentation. The paintings are

not just decorative but incredibly accurate,

and each herbarium sheet has a fascinating

layered history.”

Despite spending four months in

Madras searching for clues, Henry

was unable to discover any more

details about the artists themselves.

“It was relatively unusual at the time

to credit the artists,” he says.“I’d be

interested to know what they were

doing before this Scot commissioned

them to paint plants for him. They may have

worked in temples painting religious stories,

or perhaps they were cloth painters.”

While the details of the artists’ lives may

be lost, this project ensures that their work

will be conserved, celebrated

and appreciated by a

far wider audience.

Indian treasures unearthedIn ‘Gifts to the Garden’ of the autumn 2003 issue, we reported a

£10,000 donation toward the conservation of watercolours

commissioned by Robert Wight. Here’s the story behind the story.

The Garden has secured additional funds

from Scottish Executive Environment and

Rural Affairs Department (SEERAD). Over

the next two years £5.6 million will be

awarded for essential maintenance at all

four Gardens, and for building and

extension to the Herbarium at Edinburgh.

RBGE has been awarded a Darwin

Initiative grant of £156,022 over three years

for a project in Lao People’s Democratic

Republic, south-east Asia. Lao PDR is rich

in biodiversity but poor in resources. The

project will provide training in tropical

botany, will pave the way for the first

National Species and Threatened Plants

database and will promote collaboration

between protected area authorities and

research institutions in Lao PDR.

Last year, commemorative giving (tree

adoption and garden plaques) generated

over £23,000 plus £3,639 in gift aid. It is

becoming an increasingly important way of

supporting the Garden’s activities.

An award of £10,000 from the Scottish

Executive under the Entente Cordiale will

enable the major outdoor exhibition Earth

from the Air to come to RBGE this summer.

A Copus grant of £5,850 from the Royal

Society supported the ‘Real Life Science’

events presented at the Botanics in April as

part of the Science Festival.

RBGE is grateful for sponsorship-in-kind

to the value of £5,000 from law firm DLA

towards legal work costs for Visitor

Gateway consultant contracts.

The Royal Botanic Garden Edinburgh

welcomes grants and donations to help

continue its plant conservation, scientific

research and education programmes in

40 countries worldwide; and to provide

visitors to its four Gardens with a

welcoming experience. Here’s a round up

of recent gifts.

Gifts to the Garden

hough the Botanics is held in great

esteem and affection locally, few people

realise the extent of the Garden’s work

in research, education and conservation,

and so the impact that RBGE makes on the

world stage is not felt here.

The only time Garden staff

are visible to visitors is

when tending living

collections. Most of the

work – whether plant

hunting in the Himalayas,

studying specimens in the

Herbarium, or drafting conservation

legislation – takes place behind the scenes.

The new Gateway project sets out to

open those doors, and to ensure that all

visitors are welcomed with the opportunity

to discover all they want to know about the

Garden, and to explore ‘green’ issues.

“With over 700,000 visits per year, we

have a unique opportunity to tell people

about biodiversity and conservation,” says

RBGE Head of Development Mike

Robinson. “The Gateway is an ambitious

project, but its message is vital. Increasingly,

people are not experiencing wildlife and the

countryside first-hand. If we cannot

reconnect people with nature, we’re

heading for serious problems in the future.”

The Gateway, like the Garden itself, will

be a multi-faceted experience. It will be a

gateway in the literal sense, through which

visitors will enter the Garden. Once inside,

exhibitions, interpretation and contact with

staffwill provide a gateway to an

understanding of the Garden’s work and

conservation as a whole. This will

open a gateway to a greater

awareness of the natural world.

“ We are designing a visitor

experience for the 21st century”,

says Director of Public Programmes

Ian Darwin Edwards. “We want to

create a space that will be ever-

changing and full of topical interest – not

just what’s in flower in the Garden, but

what’s happening in the world today.

“Many visitor attractions are based on

computer interactions, but we are

developing the concept of ‘real life science’.

The Gateway will be a dynamic

environment with the buzz of a newsroom,

including live video and satellite links, so we

can connect with colleagues at field stations

and other botanic gardens.

“ We won’t just provide entertainment –

we hope to change the way people feel and

behave. Whatever their reason for coming

to the Garden, we want visitors to have an

uplifting, enriching experience.”

he cool, almost montane conditions

Dawyck provides for the cultivation of

plants complements the warm,

temperate climate of Logan in Galloway

and the oceanic climate of Benmore

in Argyll.

The grounds that visitors walk through

today is the woodland garden of what was

a considerably larger and older designed

landscape, parts of which can still be seen

from the Botanic Garden. This designed

landscape is the result of three families’

creative efforts over the last 300 years.

The first family known to have owned

Dawyck was the Veitch family (1491 to

1691). They are credited with introducing

the first exotic tree species to Scotland at

Dawyck. A survivor from this era, a

European silver fir (Abies alba) planted in

1680, still stands in Heron Wood.

The next family to own Dawyck were

the Naesmyths (1691 to 1890), great

improvers who continued the tradition of

first introductions at Dawyck. They were

largely responsible for the planning and

construction of the designed landscape at

Dawyck in the mid-1800s. This coincided

with the intrepid Scottish plant collector

David Douglas’s expeditions to the Pacific

Northwest of America, which resulted in

many tree introductions to the UK. One of

these, the appropriately named Douglas fir

(Pseudotsuga menziesii), planted at

Dawyck in 1840s, is a

majestic sight today.

The Balfour family

purchased Dawyck in 1890.

F.R.S. Balfour, the son of the

new owner, considerably

enhanced Dawyck’s

reputation of being among

the richest collection of

trees in the British Isles. The early 1900s

saw two now famous plant collectors

travelling in China: George Forrest (in

Yunnan Province) and Ernest Wilson (in

Sichuan Province). The climatic conditions

at Dawyck favoured Wilson’s introductions

from cooler Sichuan Province, with Wilson

himself visiting Dawyck in 1911 and 1922 to

see how his collections were faring.

In 1978, Dawyck became part of the

Royal Botanic Garden Edinburgh. Initial

work concentrated on the removal of

dangerous trees and the construction of

new paths to make the Garden safe and

accessible to visitors. Simultaneously, large

areas were cleared of invasive growth in

preparation for the first plantings of wild

origin plant material, allowing Dawyck

to fulfil its potential as a

botanic garden.

In recent years the search for

new wild origin plant material has

taken me on plant collecting trips

to China, Nepal and Japan. Ten

years after the first of these, new

introductions are beginning to

flower and fruit for the first time.

Dawyck has benefited from pioneering tree

planting by previous generations. Now we

are planting for the future.

Today, visitors can marvel at the majestic

historic trees by following the David

Douglas Trail, or learn more about the

threats facing our own native flora by

following the Scottish Rare Plant Trail. At

different times of year a network of paths

lead the visitor through carpets of

snowdrops and daffodils, pools of

Himalayan poppies, lush herbaceous

plantings or outstanding autumn colour.

Our priority for the future is to improve

physical and intellectual access to the

collections via new paths and bridges,

and the provision of interpretation in

the Garden.

A hidden gem in the Scottish Borders celebrates its silver jubilee this year. Twenty-five years ago, Dawyck Botanic Garden near Peebles

became the third Regional Garden of the Royal Botanic Garden Edinburgh. Curator David Knott reflects on its past and future.

What is the Royal Botanic Garden Edinburgh to you? A place to admire plants from all

over the world? A beautiful park to bring the kids on a sunny day? Or a world-renowned

scientific institution? Whatever your perspective, the answer is all this and much more.

abrielle first visited Logan on a college

study tour, and two things made a

memorable impact on her: the first was

Curator Barry Unwin feeding the students

fiery leaves of Drimys. “It was like eating raw

chillies” – and the second was the strange

sensation that the geography of Britain had

turned upside down.

At the time she was studying at the

Somerset College of Agriculture and

Horticulture and it felt incongruous to travel

so far north and find herself

in a gentle climate among

Chilean flame trees,

Brazilian gunnera and

Tasmanian tree ferns.

“I was amazed to see

plants growing in Logan

that we couldn’t get away

with in Somerset,” she says.“Though

Somerset has a mild climate, it is slightly

wetter with a heavier clay soil, and a lot of

species such as the Mediterranean plants

need a sandy, free draining soil –

the difference in soil can matter as much

as temperature.

“There are plantings at Logan that are

generally thought of as only suitable for

growing outdoors in Cornwall and the

Channel Islands. I’ve seen many of those

gardens and Logan is so much better! I don’t

think people realise quite what a unique

environment we have here, and how much we

can achieve horticulturally.”

Gabrielle had initially trained as a

veterinary assistant, but she missed the

outdoor life and so changed to horticulture –

fulfilling early indications that she would

become a ‘plantsman’:“I was always in the

garden, even as a young child. My mum has a

horrendous photo of me in a saggy nappy

with a trowel in my hand!”

After graduating in horticulture from

Somerset College, she came to RBGE to study

towards the Diploma in Horticulture

Education, and it was here that she met her

husband Colin Belton, then the Garden’s

Technical Officer.

Gabrielle moved to Logan in

2001 to join Colin, who had been

appointed Garden Supervisor,

and Gabrielle now freelances as a

gardener and garden advisor.

Living at the Garden in one of

the staff cottages means the

luxury of 24-hour access –

Gabrielle is fond of strolling through Logan

on summer evenings, enjoying the night

scents and the bats flitting about the trees.

“I love the peace and tranquillity at

Logan,” she says.“And the continual sense of

discovery – there is always something new to

see. My favourite place is probably the

viewpoint looking across the Garden to the

Galloway hills. I also have a soft spot for the

Terrace: you can hear the Garden from there,

becoming more aware of bird song in the

trees behind and the bees buzzing away in the

big patch of echiums.”

The Logan Regional Committee has been

gaining momentum with regular Members’

events such as garden demonstrations and

guided walks. As the newly-elected Convener,

Gabrielle is building up the profile of the

group and has a varied programme planned

for the year ahead. Events this summer

include the Galloway Garden Festival, a

family fun day out and a visit to Edinburgh

with a tour of the herbarium and library. This

year’s ‘Gardeners Question Time’ at Stranraer

Library in August will feature TV presenter

Ian Billet of Simply Gardens, along with

Logan Curator Barry Unwin and other home-

grown experts!

These events are open to all Members,

and, as well as encouraging people locally to

join the group, they are also a perfect

opportunity for Members in other areas

to visit Logan, which is at its most glorious

in summer.

are a vital part of the life cycle of a

plant, allowing sexual reproduction.

While many floral favourites are

pollinated by flying insects, there is a

secret world of plants pollinated by

crawling insects.

You may have marvelled at the

giant flowers of Aristolochia, found in

the Glasshouses at the Royal Botanic

Garden Edinburgh.This plant is pollinated by

flies, attracting them with its flesh-like colour

and foetid smell. In the same family,

Aristolochiaceae, Asarum species are herbaceous

plants whose ground-level flowers are often

pollinated by ants. Asarum species are

found in China, Japan, America and Europe.

They enjoy a moist, shady situation in acid soil,

spreading by creeping

runners to give good ground

cover and are hardy to at

least -15°C.

Many have leaves which

rival cyclamen for their

intricate patterns, but peep

below the leaves from June

until September and you will

be astounded by the complexity of the flowers.

Hard and waxy, often with rings of hairs,

they have a musky odour and seem irresistible

to ants.

Perhaps the best for foliage effect is Asarum

hartwegii from northern California, which has

stunning silver veins. Asarum maximum from

China has large flowers which rival

Auricula primulas in their complexity

of colour and texture.

The flowers of Asarum are followed by

small black berries.These are also favoured

by ants, who happily haul the fruits

around the garden, so seedlings may

appear many metres from their parent

plant. If you wish to try propagation by

seed, it is best sown in a cold frame as

soon as it is ripe in the early autumn.

Stored seed will require three weeks’

cold stratification and should be sown

in late winter. It germinates in spring, in

about four or more weeks at 18°C.They

can also be propagated by division of

the runners in spring and autumn.

On a walk around any of Scotland’s

National Botanic Gardens you’ll see a vast

range of flowers pollinated by insects,

cacti pollinated in the wild by bats and

Puya species by humming birds.

However, in the Peat Garden, Rock

Garden and Alpine Yard, where

asarums flourish, the action is at

ground level.

Creature ComfortsCatering for insect visitors can bring a new dimension to your garden, creating a

fascinating hub of activity for some of nature’s most industrious creatures. Pete

Brownless suggests a rather unusual family of plants for this purpose.
