The results of studying the introduction populations of 5 scantily distributed perennial species in the long-term display of “Rocky Garden” are presented. Area, occupied by each of the species population, the number of plants in it, their density, projective covering of certain species has been determined. Peculiarities of the age-grouping structure of the populations are under consideration. It is determined, that all populations under investigation are at the third stage of introduction population formation – the potential one.
