One of the important directions of research works in the field of an introduction of plants is creation, studying, enrichment and preservation of a gene pool of a floral kingdom. Species and cultivars of the genus Rosa long since draw attention of researchers thanks to their wide use in decorative gardening and industrial floriculture. Results on an introduction of representatives of the genus Rosa in Ukraine are presented in article. The collection of roses of the Kremenetsky botanical garden on 2017 totals 28 grades entering into 5 garden groups (tea hybrid, tiny, park, long-stemmed, floribunda). Introduction of studying it was carried out taking into account ecological and biological and decorative features of roses. On abiotic ecological factors of a cultivars of roses belong to facultative geliofita, mesokserophita, mesophites. According to distribution of cultivar behind garden groups more cultivars of the roses relating to the tea hybrid are represented in a collection - 10 species (35,7 %) of all collection, the smallest group park – 1 (3,5 %). Grouping kinds after the terms of beginning and end of vegetation and flowering, it is marked by us, that after beginning of vegetation the sorts of roses belong to the group early spring – 100 %, duration of vegetation: to the group of long-hauling – 100 %, sometimes flowering is prevailed by a group late afternoon – 43 %, duration of flowering middleweight – 96,5 %. Grouping the types of roses it is possible to create the garden of their continuous flowering in a period from May for August month. Entered first-ever into the phase of dying off on October, 20 – 'Veilchenblau', 'Ledy gay', 'Sophia of loren', later in all on November, 7 – 'Wartburg', 'Landora' and other.The phenological observations made by us during the period from 2012 to 2016 behind 28 species which grow on a collection site of a botanical garden, allowed to establish that the vast majority of the species represented in a collection blossom and fructify annually.
