ORNAMENTAL PLANTS IN THEIR NATURAL HABITATS
C. Kazakstan
The northern chain of the Tien Shan (the Zailiyskiy Alatau) is
situated in Kazakstan. This range is dominated by Talgar peak that
reaches a height of 5,017 m (16,456 ft). 22 other mountain peaks
reach over 4,500 m (14,000 ft) high, and their slopes are often steep
and covered with ice. The valleys of the Great and Lesser Almaatinka
rivers bisect the range, and these gorges can be reached from Almaty
(Alma-Ata), the former capital of Kazakstan. The headwaters of the
Great Almaatinka rise in the glaciers of the central part of the range.
Here, the number of plant species appears greater in the subalpine belt.
The foothills support steppe vegetation, and in early spring they are
covered with flowering annuals and perennials taxa such as the
violet-flowered poppy Roemeria hybrida, and the bright red-flowered
R. refracta, several yellow-flowered plants Trigonella orthoceras,
Hypecoum pendulum, Tulipa kolpakowskiana and Gagea capusii. In
late spring and early summer, the blue-violet blooms of Ixiolirion
tataricum and the white and violet-flowered Astragalus
schmalhausenii begin to show. The steppes are dominated by various
feather grasses, Stipa. Shrubs and trees are abundant on the
northeastern slopes of the foothills. Of especial interest here the
relictual shrub Atraphaxis muschketovii (Polygonaceae), which is
endemic to the Zailiyskiy Alatau. Common in broad-leaved decidous forests,
its bushy crowns reach up to 1.5 m (5 ft) high and are extremely attractive
in May and June when they produce masses of white-flowered racemes borne
on leafless lateral branches. Its perianth is white, and the interior
lobes are 8-9 mm in diameter. Other common shrubs include the
yellow-flowered Rosa platyacantha, Lonicera tatarica and Berberis
sphaerocarpa, showing color when flowering or fruiting. The elegant
maple Acer semenovii bears bright red fruits, and a wild apricot
Armeniaca vulgaris [=Prunus armeniaca] produces delicate pink flowers
in spring and purple foliage in the autumn.
Malus sieversii, a regional apple tree 2-10 m (6-30 ft) tall,
flowers in spring and yields abundant fruit in autumn. The city of Almaty,
which means "Father of Apples," derives its name from this apple species,
which grows mainly at the base of northern slopes. Hawthorn Crataegus
chlorocarpa and barberies Berberis sphaerocarpa, both bearing
edible fruits, are among the showy and useful shrubs. Berberis iliensis,
a rare shrub to 3 m (10 ft) tall, is particularly outstanding, attractive in
its numerous yellow flowers and bright red fruits. Spruce Picea
schrenkiana is abundant in the mountain forest belt. The conspicuous
herbaceous cover of the spruce forests includes the ornamentals monkshood
Aconitum leucostomum, colombine Aquilegia karelinii,
thorow-wax Bupleurum longifolium and dragonhead Dracocephalum
integrifolium. Growing in areas northeast of Almaty, Phlomoides
zenaidae is a rare species closely related to Jerusalem sage, with
creamy large flowers. Among the subalpine and alpine species of ornamental
significance that grow along the shores of the Great Almaatinskoe Lake is
onion Allium monadelphum, which has a remarkable globose inflorescence
of dark purple or yellow flowers. There is a low growing pink-flowered
aster Aster alpinus, the white-green flowered gentian Gentiana
algida, cranesbill Geranium albiflorum with its white bell-shaped
flowers. Also here is a particularly beautiful lousewort Pedicularis
alberti with pink-purple flowers in dense inflorescences and meadow rue
Thalictrum minus which looks like a yellow cloud when in bloom.
Speedwell Veronica alatavica with white flowers in spike-like raceme
is a rare plant that grows on the stony banks of the Tau-Chilik river.
Cortusa brotheri with its bright flowers attracts everybody's attention.
Further up the alpine and subalpine areas of the basin in Great Almaatinka
river are not easily accessible.
The high elevation zone and even the glaciers can be reached from Almaty
within half a day’s journey by travelling along the gorge of the Lesser
Almaatinka river. The river valley narrows at the confluence of the
Butakovka stream. Here pink-flowered foxtail Eremurus robustus and
the large, bright yellow-flowered Phlomoides speciosa dominate the
foothills during the spring, with the gas plant Dictamnus angustifolius
following in June. The last is a beautiful but caustic plant that causes
burns when touched. The other ornamental here is a spurge, Euphorbia
lamprocarpa with its bright inflorescence. Strikingly, apple-tree
forests that consist primarily of apple tree Malus sieversii grow on
the slopes and in the river valleys. At 1,000-1,300 m (3,280-4,260 ft)
apricot Armeniaca vulgaris [=Prunus armeniaca] forests frequently
mix with hawthorne Crataegus almaatensis and maple Acer semenovii.
Heading up the gorge, one reaches the famous Medeo skating rink, the slopes
near this abundant with forest-meadow plants, which are mostly tall
herbaceous species such as Ligularia macrophylla, monkshood
Aconitum soongaricum, cranesbill Geranium collinum and
bellflower Adenophora himalayana. The cone-shaped Mokhnataya Hill
(2,600 m/8,530 ft) has a steppe vegetation dominated by fescue Festuca
rupicola, and other perennials such as Bistorta elliptica and
Dracocephalum ruyschianum. The ridge from Medeo leads upward to
stony cliffs and big rocks which are traces of an ancient glacier. Here,
the alpine plants are represented by species similar to those of the Tien
Shan and Altay. Noteworthy for cultivation, Callianthemum angustifolium,
C. alatavicum both are low growing plants only to 5-15 (2-6") cm high
but produces dramatic white flowers 2-3 cm (0.8-1.2") wide. It is
interesting to note that its basal leathery leaves are undeveloped at
flowering time. The buttercup Ranunculus transiliensis has
diminutive stems 7-15 cm (3-6") high over shadowed by yellow flowers
2.5-3.5 cm (1.0-1.4") across. One can see an unusual violet Viola
altaica with very large flowers, 2-4 cm (0.75-1.5") across, as well
as a globeflower Hegemone lilacina with blue flowers and dissected
leaves.
Cushion pinks of Thylacospermum caespitosum are found in the
alpine meadows and among the stone deposits of the Talgarskiy Pass
(Talgarskiy Pereval). Because of their unusually dense structure, these
tough cushions are so resistantly compact that one can stand on them. The
plant is excellent for the dry rock garden. Sibbaldia tetrandra from
the rose family forms much flatter and softer cushions. The first species
occurs in Central Asia and the Himalaya, while the latter has relatives in
northern Tibet. Pyrethrum [=Tanacetum] leontopodium is a beautiful
small plant with a snow-white velvety felt along with Papaver
tianshanicum, a vibrant orange poppy, are both endemic to the Tien Shan.
Various parts of the Tien Shan contribute numerous potential horticultural
plants that are suitable for growing in diverse climatic conditions. In
addition to the species discussed above, others worth mentioning include
Niedzwedzkia semireschenskia (bignonia family) which has tubular
funnel-shaped pink flowers, the tall growing Corydalis semenovii
(dutchman breeches family), the crimson-flowered Bergenia ugamica
(saxifrage family), bright red-flowered Morina kokanica (morina
family), pink to purple-flowered Paeonia intermedia (paeony family),
with flowers ballooning to 12-14 cm (4.7-5.5") in diameter, the tiny bulbous
Iridodictyum kolpakowskianum (iris family) as well as a tall perennial
stonecrope with thick rhizome, Clementsia semenovii (crassula family).
