Under growing urbanization, a range of ornamental plants in the conditions of Black Sea Cast can be expanded by using local wild species, in particular, from the richest Abkhazian flora. As candidates, the rare and disappearing species are preferable. Their cultivation and introduction contribute to keeping up a biodiversity and are in accordance with the modern trends in landscape design. In our investigation, a geobotanical description was made for inhabitance in situ of Campanula alliariifolia Willd., C. bzybica Jabr.-Kolak., C. соrdifolia C. Koch., C. leskovii Fed.,С. lon-gistyla Fom., C. mirabilis Alb. in Gagra and Sukhum districts, in the basins of Zhayuapsy, Gumista and Bzyb rivers, in environs of Blue Lake and in the Pitsunda-Myuserskiy reservation in the Republic of Abkhazia. The abundance of species, the height of locality above the sea level, the slopes inclination and exposure, illumination, the soil layer of the basic roots’ occurrence and soil characteristics were estimated. On the ecological parameters, all studied species can be divided into two groups. The first one includes the inhabitants of steep Eastern slopes. These species can grow in the lit rocky gardens and containers with good drainage. The plants which make the second group occupied the Western and less steep slopes, and they can be cultivated in parks and gardens under a slight shade.
Keywords: introduction, сampanula soil, locality ecology, Abkhazia.
