SPECIES DIVERSITY OF FLOWER GARDEN ORNAMENTAL PLANTS IN STREET PLANTINGS OF THE NAHIRNYI DISTRICT OF THE CITY DNIPRO

The optimization of urban landscaping largely depends on the condition of gardening facilities. Greening of urban areas allows to increase the landscape attractiveness of cities and create a comfortable sanitary and hygienic environment for people. Floral ornamental plants play an important role in preserving the mental health of the population of megacities, as they have a significant positive emotional effect on people. Flower gardening improves the aesthetic appearance of cities and towns. In order to effectively and rationally carry out flower gardening, it is necessary to conduct a detailed survey of it in different functional areas, especially in megacities where unfavorable environmental conditions for the population are formed. The aim of the work is to determine the taxonomic composition of ornamental flower plants, their occurrence, and the index of dominance in flower beds of the surveyed streets of the Nahirnyi district of Dnipro. It has been established that herbaceous ornamental flower plants of 63 species belonging to 25 families are used in the design of flower beds of the surveyed streets. It was found that the largest number of species is represented by the family Asteraceae Dum. (23). It is shown that the representation of species in the genera is small, the largest - in Tagetes L., Iris Tourn ex L., Hosta Tratt., Rudbeckia L. (3 in each). t has been found that flowering perennials (18 species) are most widely represented in flower beds, to a lesser extent – flowering annuals (12), including perennials grown as annuals, and the least represented are carpet and border perennials (9) and leading perennials (8), climbing ornamental flower plants in landscaping. It is recommended to increase the number of species of biennial and bulbous ornamental plants in the landscaping of the streets of the Nahirnyi district of Dnipro, to diversify the plantings with ornamental cereals and decorative foliage plants, to plant mainly drought-resistant plants in flower beds without watering, to use climbing plants for landscaping fences.
