The South-East Coast of the Crimea has been developing as recreational region. Green planting is one of the factors that improve its recreational attraction. So it is important to study cultivated here arboreal trees and shrubs for perfection their assortment for landscape gardening. We analyzed taxonomy and biomorphological structure, botanicgeographical origin of dendroflora, the history of introduction, and the present state of cultivated arboreal plants. At present cultivated dendroflora totals 229 species belonging to 107 genus of 27 families. Magnoliophyta occupies 86,0 % of species diversity and the leading role among them belongs to Rosaceae (27,4 %), Oleaceae (6,6%), Leguminosae (5,6%). Pinophyta occupies 14,0 % of species diversity and the leading role belongs to Cupressaceae (50,0 %). Species of Mediterranean flora dominate (31,4 %). The most of them are well adapted to local climatic and soil conditions and provide “Mediterranean” appearance to cultural landscapes. More than a half (62,9 %) of the species diversity are deciduous trees (38,4 %) and shrubs (24,5 %). The proportion of evergreen plants is lower: coniferous trees – 13,5 %, and evergreen shrubs – 13,1 %. Selecting assortment of ornamental arboreal trees and shrubs should correspond to their ability to withstand summer drought and winter low temperatures.
