It is shown that umbrella papyrus (Cyperus alternifolius L.) is a more competitive species compared to small-leaf spiderwort (Тradescantia fluminensis Vell.), dwarf lilyturf (Ophiopogon japonicus (Thunb.), vleilelie (Ker Gawl) and Buddha coconut (Сissus alata Jacq.) Compositions in which umbrella papyrus is in the minority in relation to the indicated species (1 : 3 ratio) have a better developed above ground part, and also have high phytoncidal activity. The effect of the interaction of the studied species, i.e. the change in plant productivity is not due to allolopathy. The maximum phytoncidal activity is observed in monoplantings of umbrella papyrus 33–51 %, in other species their phytoncidal activity in monoplantings is lower. In joint plantings, the greatest phytoncidal activity is observed when umbrella papyrus is in most or equal quantities with other species: with small-leaf spiderwort (Тradescantia fluminensis) (36–38 %), dwarf lilyturf (Ophiopogon japonicas) (26–39 %), Buddha coconut (Сissus alata) (30–33 %).
