Bioecological features of 510 species (191 genera and 50 families) of herbaceous perennials of the world flora collection of the Donetsk Botanical Gardens of the NAS of Ukraine have been studied. We have identified the promising 337 species and recommended them to be used in greenery planting in the Steppe zone of Ukraine. The high degree of adaptation to the introduction in the region is typical for North American, Asian, European-Asian, Euro-Mediterranean-Asian, Eurasian, Eurasian-North American bulbous geophytes of steppes and forests of the temperate zone, and mid-latitude mountain areas; East Asian, Siberian-East Asian, West Asian, West Asian-Mediterranean-European, Eurasian, North American rhizomatous geophytes of forests and plains of the temperate zone, as well as of cliffs, rocky slopes of the mid-latitude mountains. The high success introduction is characteristic to non-rosellate rhizomatous hemicryptophytes of North American, European and Eurasian origin, semi-rosellate taproot hemicryptophytes of Siberian-Asian and Caucasian-Asian origin. The high degree of adaptation to the conditions of the Steppe zone of Ukraine was noted in European and Euro-Mediterranean, Euro-Mediterranean-Asian, European-Asian non-rosellate tap-root and rhizomatous hamephytes-dwarf semishrubs of rocky habitats; in Euro-Mediterranean, Mediterranean, North American non-rosellate cluster-rhisomatous hamephytes-dwarf semishrubs of rocky habitats and forests. We have identified 161 species, capable of self-spreading in the Steppe zone of Ukraine through the formation of a viable self-seeding, and 50 species with vegetative mobility. The most adapted to the climatic conditions of the Steppe zone of Ukraine are spring green ephemeroids with a period of summer-autumn-winter dormancy, long-vegetating autumn-winter-spring-green species with summer dormancy and long-vegetating spring-summer-autumn species with a period of winter dormancy.
