The rare decorative groups of plants are established and their synphytosozological estimate is described. The perspectives in landscape and shade gardening of usage of the studied plants are substantiated. The main types of phytocoenotic compositions and landscape phytocoenotic design are analyzed, besides the models of phytocoenotic compositions of rare phytodiversity are suggested.
