ORNAMENTAL PLANTS IN THEIR NATURAL HABITATS
The Far East
The Russian Far East extends over 3.500,000 square kilometers
(1.350,000 sq miles), stretching between East Siberia and the Pacific
Ocean. Cape Dezhneva, discovered in 1648 by the Cossak Dezhnev, is the
easternmost point in Asia, situated at longitude 169°39' W. The
Russian Far East includes the Primorskiy and Khabarovskiy Territories
or "kray" in Russian, the Amur and Magadan Regions, the Kamchatka
Peninsula and the Sakhalin, Kommandorskye and Kuril Islands (Kuril’skye
Ostrova). The Arctic Ocean forms its northern boundary and the Bering
Sea, the Sea of Okhotsk and the Sea of Japan lie at its eastern shores.
The southern boundary of the Russian Far East runs along state frontiers
with China and Korea. This region is of great interest for botanists,
geologists, and even volcanologists, about 100 volcanoes occur on
Kamchatka and 20 of them remain active.
The southern part of the Far East is the richest one, and therefore,
of the most interest to botanists. This area belongs to two floristic
regions: 1) the Manchurian and Sakhalin-Hokkaido Provinces of the Eastern
Asiatic Region; and 2) the Transbaykalian Province of the Circumboreal
Region (Takhtajan, 1986). This encompasses the southern part of Siberia,
territories along the Amur river, Primorskiy Territory including the
Sikhote-Alin ranges and the Lake Khanka area, south as far as the Amur
Gulf, the southeastern portion of the Onon-Argun steppes (Dauria Ononskaya
and Dauria Argunskaya), most of Sakhalin Island as well as the southern
Kuril Islands. The mountains of the southern Far East originated in the
late Cretaceous and early Paleogen (Krishtofovich, 1932). All ranges on
the continent and on Sakhalin Island run parallel to the coast. The
highest peaks in the region reach 2180 m/7,150 ft (Bureinskiy Ridge),
2,078 m/6,816 ft (Sikhote-Alin Ridge) and 200-700 m/700-2,300 ft (East
and West-Sakhalin ranges). Conditions in the Quaternary period
facilitated the survival of certain remarkable plant complexes in
Primorskiy Kray as well as in the southern part of the region near the
The vegetation cover of the Russian Far East is diverse. The luxuriant
woody flora predominates in the Primorskiy Kray and the Amur River region,
southern Sakhalin and the southern Kuril Islands and consists almost
entirely of deciduous forests. This is a basic feature distinguishing
this provincial vegetation from that of adjacent regions in Siberia.
Prairie-steppes and meadow-steppes are common on the Prekhankaiskaya and
the Zeya-Bureyskaya plains. The Manchurian province is characterized by
high endemism, including Microbiota (M. decussata), the only endemic
coniferous genus within the flora of the FSU. The Sakhalino-Hokkaido
province has a considerable number of narrowly endemic species. Among
four Far Eastern generic endemic the most interesting is Miyakia
(Ranunculaceae) that occurs only in East Sakhalin Range.
The total number of ornamental species cannot be accurately determined,
because no such an analysis has been done. However, regional studies of
individual areas give us a fairly adequate picture of its introduction
possibilities. Thus, from the southern Far East more than 150 species of
ornamental perennial plants were offered . 250 species taken from Sakhalin
and the southern Kuril Islands were tested in different botanical gardens.
The rich herbaceous cover of the Far Eastern broad-leaved forests can be a
source for not less than 125 species. These potentially new horticultural
herbs can be grown in temperate zones.
Taxonomic studies of the flora of the region show that the buttercup
family, Ranunculaceae, is one of the richest in ornamental species,
including the genera Aconitum, Adonis, Aquilegia, Cimicifuga, Delphinium,
Trollius. Less numerous but well represented are
the daisy family with the genera Artemisia, Aster and
Heteropappus, the bellflower family including Adenophora, Campanula,
Codonopsis and Platycodon, the lily family (s.lat.) with
Fritillaria, Lilium, as well as the saxifrage family including
Astilbe, Bergenia and
Saxifraga. Several genera in the Far
East have numerous ornamental representatives. The genus Viola
(violet or pansy) has ca. 40 species and Aconitum (monkshood) ca.
30 species. Classical horticultural genera such as Rhododendron, Lilium,
Geranium, Corydalis and Pulsatilla contain about
10 species each. The Far East also includes some native taxa that gave rise
to large horticultural complexes. Among them are Callistephus
chinensis, the ancestor of the cultivars of the annual China aster, and
Paeonia lactiflora that served as the initial germplasm for the almost
entire multiplicity of paeony cultivars. Both species came into the garden
worldwide from China.
Numerous interesting plants grow in the vicinity of Vladivostok and in
the surrounding areas. Botanical excursions can be made around the locales
of the Okeanskaya station and the Bay of Tikhaya, Kiparisovo (Nadezdinskiy
district), Anisimovka (Shkotovskiy district), Dalnegorsk as well as Popov
and Reinike islands. Each of these has diverse plant communities, but by
far the most fascinating place is the "Kedrovaja Pad" reserve.
The "Kedrovaja Pad" reserve was founded in 1916 and is one of the oldest
in the country. The reserve is situated in the Primorskiy Region on the
west shore of the Amur Bay. The reserve covers 1,800 hectares (ca. 4,400
acres) across the foothills of the Chorny Mountains. The Sukhorechenskiy
and Gakkelevskiy ranges that cross the reserve have an average of
300-400 m (1,000-1,300 ft), and the highest peak, Uglovaya, is 700 m
(2,300 ft). All the northern slopes are gentle, whereas the southern
slopes are steep and rocky. The climate of this region differs very much
from that of the other Far East regions, for it is under the influence
of tropical cyclones, which is especially important during the growing
A visit to the Kedrovaja Pad reserve provides a wonderful opportunity
to get to know a unique type of forest, peculiar in its richness. The
unusual appearance of these forests results from the striking abundance
of epiphytes, vines and woody lianas that wind around tree trunks to
lengths of 20 m (65 ft) or more. The impression is that of a tropical
rain forest, but here the main tree species are Manchurian fir Abies
holophylla, Mongolian oak Quercus mongolica, Manchurian ash
Fraxinus mandshurica and poplar Populus maximowiczii. Some
trees, for example an elm, Ulmus japonica, are as tall as 30 m
(100 ft) or more. The understory consists of many woody and herbaceous
species among them a number from the ginseng family Araliaceae: Aralia
continentalis, A. cordata, A. elata, Eleutherococcus senticocus, E.
sessiliflorus, Kalopanax septemlobus, Oplopanax elatus as well as
inestimable ginseng Panax ginseng. All of these are valuable
medicinal plants. Nowhere else in the FSU can botanists find as many
invaluble members of the Araliaceae as in the Far East. The Amur cork
tree, Phellodendron amurense (Rutaceae), is also characteristic
of the Far East. It occurs in clearings and valleys and one can recognize
the tree immediately by its wonderful delicate foliage, which becomes
bright yellow in the autumn. A birch, Betula schmidtii, which is
known as iron birch in Russian because of the metallic violet tint of its
dark grey bark, grows in the mountain hills. In some places, the Japanese
yew, Taxus cuspidata, catches the eye. This plant occurs in many
areas in the Sikhote-Alin and the Japanese Sea islands having various
life-forms. It can be a tall tree, a shrub with many trunks, or a dwarf
shrub with prostrate branches up to 4 m (13 ft) long. Along the sea shore,
a visitor may meet Alnus japonica, which is closely related to the
seaside alder, Alnus maritima, of North America.
Botanists have found many such pairs of closely related species, one
occuring in America the other in the Far East. The umbrella leaf
Diphylleia (Berberidaceae) is a good example. The genus has only
three species with one, D. cymosa, occuring in northeastern
(Appalachia) North America; the other two in the Far East. D. grayi
occurs on Sakhalin, in Japan, and in mainland China, D. sinensis
occurs in Japan. Other common genera have Asian-American disjunctions
e.g., the skunk cabbage genus Lysichiton is represented by the
L. camtschatcense on Kamchatka, Sakhalin, the Kuril
Islands and in the Amur River basin while another species, the yellow
skunk, L. americanum, is found in western North America;
Plagiorhegma [=Jeffersonia] dubia is distributed in the Far East,
whereas P. [=J.] diphylla is restricted to North America. There
are also some species common to these two areas. For example,
Symplocarpus renifolius of the family, Araceae, occurs in the
southern Far East as well as in northeastern mountains of North America.
The ferns Onoclea sensibilis and Osmundastrum asiaticum
[=Osmunda cinnamomea] also have disjunct distribution areas; they
grow in both East Asia and North America. There are also similar cases
of geographic distribution where only one or two species of a large
genus occur in the Far East, and all the rest of the species are found
in North America. As examples, Penstemon and Phlox could
be mentioned. There are only single representatives in the flora of the
FSU Penstemon frutescens and Phlox sibirica. Many species
of the large genus maple occuring in the Far East have their relatives in
the North America. As example the maple species, Acer ukurunduense,
which grows in the forests of the Far East, is closely related to A.
spicatum which grows in the northern and montane regions of the eastern
United States, while another Far Eastern species, A. tegmentosum, is
closely related to the American striped maple, A. pensylvanicum.
Likewise, Parthenocissus tricuspidata occurring in southern
Khasanskiy Region is closely related to the Virginia creeper, P.
quinquefolia. Oplopanax elatus mentioned above is closely related to
the American Oplopanax horridus. Many other examples could be
The Kedrovaja Pad reserve is interesting to visit in any season.
Herbaceous plants flowering from early spring till late autumn provide a
magnificent display. Adonis amurense is one of the earliest plants
to bloom, and its bright yellow flowers can be seen among patches of snow.
At the same time or just a little later, the white-blue flowers of the
liverleaf, Hepatica asiatica, and a violet, Viola rossii,
begin to appear. These plant come into flower before their leaves develop.
This peculiarity is shared by
Hylomecon vernalis of the poppy family.
Its yellow flowers are very attractive, especially when it grows alongside
the white or sometimes light blue-flowered Anemonoides amurensis.
The pink-flowered Corydalis gigantea, probably the tallest species
in the genus, reaches 1 m (3.3 ft) in height in these localities.
Chloranthus japonicus, the individual flowers of which are small
and inconspicuous still provides impressive display because its white
flowers are numerous and gathered into compact inflorescences. The species
is an unusual temperate representative of the tropical family Chloranthaceae.
Schisandra chinensis, a woody liana of the tropical and subtropical
Schisandraceae family, also grows in the reserve, and local people consider
its fruit to have valuable medicinal properties. Also of tropical origin,
the annual herbaceous liana Schizopepon bryoniifolius of the
Cucurbitaceae frequently grows among roadside shrubs. There are many other
woody and herbaceous vines in these forests. To the latter group belong
Crawfurdia volubilis of the family Gentianaceae, with robust stems
up to 1 m (3.3 ft) and bright blue flowers, Dioscorea nipponica of
the family Dioscoreaceae, with broadly ovate leaves and inconspicuous
flowers, as well as Menispermum dauricum of the family Menispermaceae,
with thin climbing stems 3 m (10 ft) or longer and remarkable bluish light
green leaves. All three vining taxa would be good garden plants.
In many places in the Kedrovaja Pad reserve one can see the familiar
Jack-in-the-pulpit, Arisaema amurense, which has an erect green
spathe with purple margins and purple or violet stripes inside.
Rhododendron shrubs make a colourful display on rocky hillsides.
Two species growing in the reserve are deciduous plants on which the
flowers appear before the foliage: Rhododendron mucronulatum ranges
to 3 m (10 ft) tall with large (5-6 cm/2-2.4" diam.) purple-pink flowers;
R. schlippenbachii reaches 2 m (6.5 ft) height and has light pink
flowers (7-8 cm/2.8-3.2" diam.) crowded at the tips of branches. This
latter species is rare in the reserve, yet is very common in Khasanskiy
Region. It is a very attractive species, and is probably the undisputed
gem of the genus in the Far East. Members of the lily family make a
magnificent display during early and mid summer. In clearings and meadows,
a profusion of lilies can be seen: Lilium buschianum, L. cernuum,
L. distichum, L. pensylvanicum and L. pseudotigrinum. All are
attractive with large and splendid flowers of different shapes and hues,
and are of outstanding beauty and very desirable for the garden. The
local daylily, Hemerocallis middendorffii, is practically unknown
in cultivation outside Russia. Its bright orange-yellow flowers are in
compact clusters at the tops of stems, and each inflorescence has four
or more flowers up to 10 cm (4") long. This daylily species deserves
special attention because of its potential value for hybridization.
Fritillaria ussuriensis may not be as attractive as the
above-mentioned species. However, it is an elegant plant with purplish
brown flowers in campanulate shapes topping stems as tall as 60 cm (2 ft)
and leaves with delicate tendril-like tips.
One of the most valuable plants in the reserve is
Paeonia lactiflora. This particular species is ancestral to many
of the cultivars we have today. These paeonies grow most frequently in clearings
and other sunny habitats. When in bloom they produce large white or pink flowers,
numerous even in the wild. Coming into flower simultaneously with the paeonies
are representatives of the bellflower family. Campanula punctata, with its
white, tubular-bell-shaped flowers, appears first of all, on river shallows and
among dense shrub woods. Certain species of lady-bells, Adenophora,
with light and dark blue flowers, grow in different forests. In mid-summer
the bonnet bellflower, Codonopsis, appears with flowers in a palette
of colors. C. pilosula has yellow flowers, C. lanceolata,
grey-green flowers, and C. ussuriensis varies to even dark violet
flowers. Balloon flower, Platycodon grandiflorus, already utilized
in gardens, can be seen in the wild here. It has broadly campanulate
(8 cm/3.1" wide), deep blue, light blue and sometimes white flowers in
corymbose inflorescences. A midsummer-flowering plant known in cultivation
is the very attractive campion,
Lychnis fulgens, with bright red flowers. There are many species which,
although currently unknown in cultivation, merit special attention. Among them are
Lespedeza tomentosa of the pea family. This perennial has numerous white
flowers in long racemes in mid-summer. At the same time one can see
snakeroot, Cimicifuga heracleifolia, with white, tiny but numerous
flowers contrasting above its dark green leathery leaves. The golden ray
genus Ligularia are gigantic, up to 2.5 m/8.2 ft (e.g. L.
jaluensis), while others reach only 0.5 m/1.6 ft (e.g. L.
Those travelling southward to the Chinese border should know that they
will arrive, not only at an administrative border, but at natural border
as well. A trip from the reserve to the south allows one to observe
certain plant species for which these regions form the northern extent of
their distribution areas. Here grows the woody liana Boston ivy,
Parthenocissus tricuspidata, especially abundant on Falshiviy
Island and on the cliffs on the cape of Golubiniy Utes. Its main
distribution area is Japan, Korea and China. Along the Japanese sea
shore another woody vine climbs vigorously on rocky places, the Kudru
vine, Pueraria lobata of the pea family. Its climbing stems to
6 m/19 ft long bear trifoliolate leaves, and large, fragrant, violet-purple
flowers borne in long axillary racemes. Aristolochia manshuriensis
is closely related to A. durior, the Dutchman's pipe, which is also
a liana with rounded heart-shaped leaves up to 30 cm (1 ft) long, and stems
up to 15 m (50 ft) tall. All three aforementioned lianas are very
attractive. Botanists and plantsmen are very impressed when they see the
aquatic plants Brasenia schreberi, Euryale ferox and Nelumbo
komarovii. They are relatively rare in the Far East today and are
considered to be vanishing species. All three belong to tropical families,
the Cabombaceae, the Nymphaeaceae and the Nelumbonaceae respectively.
To the north of Vladivostok on the Sikhote-Alin foothills, one can see
coniferous broad-leaved forests, shrub thickets and mountain tundra. There
are some ornamentally interesting taxa here including shrubs and perennials.
Among the shrubs are two rhododendrons. Rhododendron aureum is an
evergreen shrub to 0.3-1 m (1-3 ft) tall, with clusters of 3 to 5 yellow
flowers, closely related to R caucasicum, which has white flowers.
The other species is R. redowskianum, a remarkably tiny, deciduous
shrub to 20 cm (8") with purple flowers 3-6 cm (1.2-2²) in diameter. Both
species would adapt nicely to rock gardens, and many other perennials here
can also be used. For example, Artemisia lagocephala, Saussurea
sovietica and S. tomentosa are of interest in that all parts
of these plants are densely hairy with leaves covered with dense grey to
silvery-white hairs. Gentiana nipponica with dark blue flowers is
also good for rock and alpine gardens. In many places, different forms
of Bergenia pacifica can be seen, varying in the color of the
flowers and the size of its inflorescences.
Of special interest are the tall plant communities that include
herbaceous plants up to 4 m (13 ft) tall, often with arresting bold
foliage. This vegetation type can be seen in the Far East in the
southeastern regions of the Kamchatka Peninsula, on southern and central
Sakhalin (up to 52° N), on the Kuril Islands (up to 46° N) and on the
continent near the Tatarskiy Channel. The number of species is not very
large, but often includes Aconogonon weyrichii [=Polygonum weyrichii],
Angelica sachalinensis and A. ursina, Cacalia robusta [=Parasenecio],
Petasites amplus and P. tatewakianus as well as Reynoutria
sachalinensis [=Polygonum sachalinensis]. Most of these species have
very large leaves. Accordingly, leaves of Petasites amplus and
P. tatewakianus may reach 1.5 m (ca. 5 ft) across and look like
large umbrellas. Also in this plant community are found Aconitum
fischeri, Anthriscus sylvestris, Cirsium kamtschaticum, Filipendula
camtschatica, Heracleum lanatum, Senecio cannabifolius and Urtica
platyphylla. These plants grow astonishingly fast in the spring,
gaining up to 10-15 cm (4-6") in height a day with Filipendula
camtschatica. All these species can be used to form a wild garden or
as it is sometimes called, "herbaceous jungle". It is noteworthy that
these species are not as tall in other parts of their distribution ranges.
The forests of the Far East possess a wealth of
material. There are about 90 ornamentally useful species in the forests on
Sakhalin and the Kuril Islands. The early
flora is especially abundant in these forest formations. In damp and swampy places
Lysichiton camtschatense and Symplocarpus renifolius flower before leafing.
The inflorescence of Lysichiton is surrounded by a white spathe,
and that of Symplocarpus by a dark cherry-red one. Together with
these plants grows the vivid yellow-flowered Caltha fistulosa. In
southern Kunashir, the large pink trout lily Erythronium japonicum
makes a spectacular spring display on seaside terraces. On Sakhalin
Trillium camtschatcense comes into full bloom in spring and produces
bright flowers with three large white petals. Trillium is better
represented in North America but only three species grow in the Far East.
Another monocot, the gigantic lily Cardiocrinum cordatum, which
grows in the forests of southern Kunashir, attains a height of 2 m/6.5 ft.
The most conspicuous of the woody plants are the cherries Cerasus
sachalinensis [=Prunus sargentii] with their numerous large pale pink
flowers, C. kurilensis [=Prunus kurilensis], a shrub up to 2 m/6.5
ft tall with white flowers 3 cm (1.2") in diameter and C. maximowiczii
[=Padus maximowiczii], a medium-sized tree with white flowers 2 cm
(0.8") in diameter. Eight species of Viburnum occur in the flora
of the FSU and all are of great horticultural value, with five of them in
the Far East. Of especial merit is Viburnum furcatum, a shrub
2-4 m in height with large white flowers and lovely leaves, which remain
ornamental until late autumn.
Magnolia hypoleuca is the only Magnolia native to the FSU,
and it also grows in south Kunashir, producing lovely, fragrant flowers.
The shrub Hydrangea paniculata and the liana H. petiolaris
also occur in the mountain mixed forests. A native kiwi (Actinidia
kolomikta) is found in the virgin forests of the Ussuriyskiy Kray, along
with other lianas, such as Schisandra chinensis and wild grape
Vitis amurensis. The dominant forest trees are pine Pinus
koraiensis, birch Betula davurica, fir Abies nephrolepis
and Mandshurian walnut tree Juglans mandshurica. Below are
Eleutherococcus senticocus and Viburnum burejaeticum, two
understory shrubs, of which the first is an important medicinal plant.
Among the herb layer are monkshood Aconitum kusnezoffii, a plant to
1.5 m (5 ft) tall with dark blue flowers, Cypripedium ventricosum, a
large-flowered orchid, the smaller flowered orchid
Platanthera extremiorientalis, a bright red-flowered campion
Lychnis fulgens, a pink-flowered
Dianthus chinensis and meadow
rue Thalictrum filamentosum, a delicate plant seemingly misted with
numerous white flowers.
Although meadows do not occupy wide areas in the Far East, they include
more than 60 species of ornamental plants. The list includes the orchids
Amitostigma kinoshitae, Cypripedium guttatum, C. macranthon and
Dactylorhiza aristata as well as Adenophora species,
Arnica sachalinensis, Eleorchis japonica, Iris ensata, I. laevigata,
Lilium distichum and Ptarmica macrocephala [=Achillea macrocephala].
Campanula punctata, with its striking white hanging
flowers, grows in shrub brushwoods and along river shallows. The columbines
Aquilegia oxysepala, A. parviflora and A. flabellata grow in
meadows and along forest margins in Sakhalin and the Kuril Islands. Two
attractive asters, Aster spathulifolius [= A. fauriei] and A.
maakii, also grow there. In July and August Hosta rectifolia
adds a violet hue to the landscape. The plants have presumably become
wild having settled in the meadows from old neglected gardens.
The lengthy and deeply indented coastline of the Far East provides large
areas of exposed gravel slopes and ridges that support a number of
ornamental plants. The most widespread species on the rock exposures of
Sakhalin and the Kuril Islands are
Aquilegia flabellata, Dianthus superbus, Draba borealis and Saxifraga
sachalinensis. The rare plants include Orostachys furusei [=O. aggregata],
a plant with numerous flower stems, Rhodiola integrifolia, with dark red flowers
and speedwell Veronica grandiflora, a tiny plant but with flowers
1.5-2 cm (0.6-0.8") in diam. Bergenia pacifica, Chrysanthemum
zawadskii [=Dendranthema zawadskii], Orostachys malacophylla, Rhododendron
schlippenbachii, R. sichotense, Scutellaria baicalensis and Sedum
kamtschaticum are among the rock plants of the continental Far East.
There are about 50 species of ornamental plants that grow in the rocky
habitats of the islands, of which 20 occur on the continent.
Among the endemic taxa, the most peculiar is Miyakea integrifolia,
a generic endemic of Sakhalin. Although most Russian botanists treat
Miyakea as a distinct genus, others include it in Pulsatilla,
pasque-flower, because of the similarity of their flowers. The differences
are that the monotypic Miyakea has simple, ovate to oblong, glossy
leaves with recurved margins, whereas all Pulsatilla species have
deeply lobed leaves. Two miniature, mat-forming bellflowers, Campanula
chamissonis and Campanula lasiocarpa, may be encountered on the
dry stony upland slopes of the Kuril Islands. The ornamental
Dicentra peregrina, a spectacular perennial with grey leaves and pink
flowers and Pennellianthus frutescens [=Penstemon frutescens] both have close
relatives in North America. Saxifraga merckii, with white flowers,
grows in stony habitats and may well be used in the rock garden. Primula
cuneifolia, a tiny primrose with umbrella-like inflorescences, grows in
