Collections and expositions of flowering ornamental plants of Donetsk Botanical Garden

The paper gives a brief description of the main collections and expositions of flowering ornamental plants of the Donetsk Botanical Garden. The features of plant exhibition are considered. The collections of the flowering ornamental plants of the Donetsk Botanical Garden at present include 1022 species, 1152 cultivated forms and varieties. The plant range is demonstrated according to a trend of large-scale collection plots and display gardens formation. Large-scale monoculture collections show diversity of ornamental varieties of major flowering crops. The collections of «Dahlia», «Iris», «Chrysanthemum», «Callistephus chinensis», «Paeonia», «Aster dumosum», «Canna», «Hemerocallis», «Rosa» are mostly represented by cultivars and species of the corresponding generic complexes. Those cultivars are exhibited mainly in row plantings and combined according to various characteristics, namely plant height, structure and color of the flower or inflorescence. As the cultivars of Hemerocallis × hybrida hort., Paeonia lactiflora Pall., Iris × hybrida hort., Rosa × hybrida hort. are the hardiest in steppe conditions, they are the most widely represented in flower collections. When forming thematic landscape show gardens, we were taking into account biomorphological, environmental and phytocenotic characteristics of plants. These landscaping display flowerbeds show decorative qualities of a wide range of ornamental flowers, trees and bushes with continuous flowering aspect, as well as landscaping design approaches. Over the last five years, the expositions of «Shade Garden», «E.N. Kondratyuk Garden», «Mexico» have been created and have been developing. Other exhibition areas such as «Demonstration Show Garden» and «Ground-Cover Plants» undergo extensive reconstruction. The necessity of introducing new species, intraspecific varieties and modern cultivars into the living collections is still relevant. New varieties are intensively selected: 23 cultivars bred by the Garden-based originators are now present in the collections.
