Cultivation of herbaceous plants of Central Asia in various expositions of the open ground of the Botanical Garden of IBBM UNN

This report considers species of herbaceous plants that have areas covering only Central Asia or C. Asia and adjacent regions of Asia, mainly within the Iranian-Turanian floristic region. Species with very large ranges, partially including C. Asia, are not taken into account. 46 species of Central Asian plants are represented in the open ground expositions of the UNN IBBM Botanical Garden, they make up only 4.6 % of the collection of herbaceous introduced plants of the Botanical Garden. More than 70 % of Central Asian plants in the collection are monocots, including 19 species of the genus Allium L. In permanent expositions, most of the plants are grown in rock gardens. The greatest number of problems arose with representatives from Central Asia due to the fact that seeds obtained from different sources often do not germinate. When grown in permanent exposures, a number of specimens of various origins turned out to be unstable, for example: Ixiolirion tataricum (Pall.) Schult. et Schult.f., Rhodiola algida Fisch. et C. A. Mey. Some plants were shortlived, such as those of the genus Juno Tratt. Regularly bloom, bear fruit, grow well vegetatively Gymnospermium albertii (Regel) Takht., Sedum pachyclados Aitch. ex Hemsl., Corydalis nobilis (L.) Pers., Allium aflatunense B. Fedtsch., A. altaicum Pall. and other onions, Fritillaria pallidiflora Schrenk, Tulipa kaufmanniana Regel, T. tarda Stapf and other tulips. Some of them are also included in the lists of seeds offered by the UNN Botanical Garden for exchange (Delectus seminum).
