The success of the introduction of plants depends on their vitality and adaptation to new existence conditions. Different adaptability of plants depends not only on the species, but also on their individual properties. The article studies the characteristics of adaptation of the perspective ornamental shrubs - Weigela, Caprifoliaceae. We have shown the variety’s morphological features, the growth and development of varieties of Weigela that have been taken during the research in the experimental Garden Center (NСRRIH&V). There is an estimation of growth rate and its dependence on the structure of different varieties of Weigela’s crown. We have examined the features of the formation of leaves: we have defined the indicators such as the number, length and leaf area; biomass, dry weight; productivity of leaves. We have estimated Weigela leaves photosynthetic activity in the introduction’s region. We have determined the number of photosynthetic pigments in the studied cultivars of Weigela’s leaves. We have found out that Weigela’s leaves pigments’ synthesis largely depends on their natural color, quality and the vegetation phase. These studies allow us to conclude that all the studied varieties of Weigela can be characterized by a high degree of adaptation and deserve widespread in Krasnodar gardens and parks due to the high decorative flowering period
