Analysis of the taxonomic composition of groundcover plants in the conditions of Bryansk

Abstract

The results of the analysis of the assortment of cultivated and wild groundcover plants growing in the conditions of the city of Bryansk, promising for use on objects of landscape architecture and in decorative gardening, are presented. The studies were conducted in the period from 2021 to 2023. In the conditions of Bryansk, 24 species of cultivated and wild-growing groundcover herbaceous plants are used, which are part of 13 families and 19 genera. The largest number of groundcover plants is represented by the families of thick–leaved (Crassulaceae) – 6 species (25% of all plants) and Clearleaved (Lamiaceae) – 5 species (21%). Two types of groundcover plants were found in the Cabbage (Brassicaceae) and Primrose (Primulaceae) families (9% of the total number of groundcover species each). In the conditions of the Bryansk region, the species of European origin have the largest representation (33% of all plants). These include: Alpine arabis, young roofing, acrid ochitok, monetted verbena, small periwinkle, creeping gum, yellow green, mottled clear, creeping thyme and European hoof. According to the color of flowers in the studied groundcover species, we identified plants with white (24.8%), golden yellow (20.2%), lilac (13.8%), pink and purple (9.5% each), cream, blue and nondescript (5.7% each) and purple (4.3%) coloring. According to the color of the leaves of the studied groundcover plants, we identified plants with light green (33%), dark green (24%), mottled (19%), purple (10%), blue (9%) and silver (5%) coloring.
