The purpose of the study is to identify the composition and analyze frequency and stability of alien plant species in phytocenoses of lawns in the central part of the Kursk city. 37 neophyte species have been identified, which is 27.4 % of the identified flora. The most common of these is Lolium perenne L. , a species that is used for sowing on lawns. Among other species, the most common are Geranium sibiricum L., Erigeron canadensis L., Sonchus oleraceus L.
