The most important challenge in the field of introduction and acclimatization should be accumulation collection funds as the main base for research. The mobilization and testing of varietal diversity of flower and decorative crops in this regard are important significance in the development of the scientific foundations of decorative gardening and landscaping. Peony is one of the most beautiful and common flower crops. With a large palette of colors and a variety of flower shapes, peonies form a bush that, thanks to carved leaves, is decorative from early spring to late fall. The article presents the results of the research of comparative-literary analysis of scientific sources with the study of foreign experience of growing Ito-peonies for the purpose of using them in landscape design. The main objective of the research was to replenish the peony culture collection on the basis of the architectural and exposition plot of the Podillya Botanical Garden of Vinnytsia National Agrarian University with new Itoh Group varieties, their introductory cultivation   and   identification   of   the   most promising decorative and valuable cultivars, cultivation, and cultivation in breeding work. The systematized and generalized data on the historical aspects of cultivation of Ito-peonies of foreign breeding are presented. The new interspecific ITO hybrids have the advantages of both parents: they took winter hardiness from grassy peonies (the aerial part dies in winter), and the shape and color of the flowers and leaves are inherited from tree-like ones. This achievement allowed us to expand the color gamut of winter-hardy peonies. During the experimental study, the use of the studied Paeonia L. species for the greening of cities, towns and private houses was found to improve the aesthetic perception of the designed objects. The original characteristics of the varieties and hybrids of Ito-peonies claimed by the originator showed the complete coincidence of varietal characteristics in all the parameters that determine their decorative affiliation. It is proved that under Podillya conditions the studied plants are characterized as valuable objects for increasing the range of flower and ornamental perennials in order to improve the condition of gardens and parks of Ukraine. According to the results of the varietal study of the American Peony Society, originality, high decorative and flowering duration in the Podillya area were established. It is proved that in addition to the high decorative properties of this group, there are also significant prospects for use in landscape  design. Ito-peonies are of considerable importance in the landscaping of populated cities, including parks, squares, boulevards, waterfronts and private plots. The study group is classified as one of the most beautifully flowering perennial flower and decorative crops. A wide range of colors, a variety of flower shapes are created, creating a bush with ornamental foliage that does not lose its decorative effect from early spring to late autumn. Thus, the Itoh Group's research for the modern landscape gardening will allow to significantly expand the range of flower and ornamental plants in order to enrich the cultivated flora of the Podillya region and Ukraine as a whole. The results of the experiment will be used to replenish the collection of the Ito group on the basis of the architectural and exposition section of the Vinnytsia NAU for the practical activity of students of specialty 206 «Landscape gardening» and scientific and pedagogical staff.
