The objective of this study was to define the diversity of Rosaceae representatives in parks and squares of Kryvyi Rih city and to evaluate their vitality, longevity, and perspectives of a further application for landscaping of the region. Material and methods. The object of our study were Rosaceae plantings in parks and garden squares of Kryvyi Rih. We used visual, morphometric, and statistical methods. Results. In the parks and squares of Kryvyi Rih, family Rosaceae is the most diverse – it is represented by 43 species, five hybrids, and five cultivars, which together belong to 20 genera. The most represented genera are Spiraea (seven taxa), Sorbus (five), Cotoneaster (four), Malus (four), Padus (four), and Prunus (four), while the rest of genera comprises from one to three taxa. The geographic analysis suggests a significant prevalence of species from East-Asian (36.5 %) and Circumboreal (34.6 %) regions. According to the distribution of life forms, there is some predominance of shrubs; they represent 56 % of the total number of Rosaceae. With regard to height classes, trees of the third class of size (34.6 %) and undersized shrubs (25 %) prevail. As for age structure, 20–40-year-old shrubs and trees (about 70 %) predominate. The highest level of the vital state is noted for 60 % of plants of this family, the average level – for 30 %, and low level – for 10 %. 72 % of evaluated plants were classified as highly decorative and 28 % as decorative. In the future, enrichment of plantings of the region may be carried out by using the collection stock of arboreal plants of Kryvyi Rih Botanical Garden of the NAS of Ukraine, comprising about 350 species, varieties, and cultivars of 31 genera of the family Rosaceae. Conclusions. Most of the investigated Rosaceae plants, in conditions of a large industrial city located in the Steppe zone of Ukraine, were characterized by high viability and decorativeness. Hence, these plants deserve to be more widely used for the greening of cities and towns of the Right-Bank of the Steppe zone of Ukraine.
