Prospects for the use of Сercis canadensis L. in construction and optimization of farmsteabs in the urban environment

The article presents information about the existence of modern anthropogenic landscapes in which a significant role is played by urban areas, the structure of which, features of functioning and ecological state depend entirely on the peculiarities of the natural conditions of the territory, as well as the culture and economic activity of the population. The most effective means of improving the environment of the urban village zones of settlements is greenery, which can minimize factors of natural and man-made origin that are unfavourable to humans. The effect of these factors and the degree of anthropogenic impact inherent in urbanized areas constantly leads to changes in the landscape structure, weakening of vegetation, premature aging and death of plantings. There is a need to select an assortment of plants that are environmentally resistant to the climatic conditions of the urban environment, to increase the area of green spaces, in particular to expand species composition of woody plants by using beautifully flowering woody species. Such plants include less common, unconventional, highly decorative species Cercis canadensis L., which is gaining popularity and is used to create plant compositions in parks, gardens and street landscaping in Ukrainian cities, where it successfully grows, creating comfortable conditions for people to live and work. In urban landscape design the plastic environmental resistance of C. canadensis plants to the climatic conditions of the urban environment and their high decorative properties contribute to their wider use in landscaping. They are suitable for woody-shrubby composite groups creating with deciduous and coniferous plants. The tentlike shape of the crown of С. canadensis provides opportunities to create monospecies group plantings that will become green islands or centres in specific areas and in general will improve the environment for people living in urbotechnogenic environment of the city, which is relevant today in the context of the environmental crisis and is not sufficiently used in the architectural and construction practice of modern Ukraine. Therefore the aim of this work was to determine the prospects for the use of С. canadensis in optimising of existing and creating of new urban areas depending on their ecological plasticity and plant growth characteristics in urban environments. Key words: Cercis canadensis, decorative properties, ecological plasticity, urban-technogenic environment, landscaping.
