Р. М. Османов The results of an introduction study of 16 species of the genus Dianthus L. in the Mountain Botanical Garden of the Dagestan Scientific Center of the Russian Academy of Sciences are presented. The variability of decorative traits of carnations and their introduction resistance in mountainous conditions was assessed. The colouring of the flowers of introduced carnations has 5 colors and shades: white, pale pinkish, yellowish-cream, pink, mauve. Based on the shape of the flower, introduced species with fringed petals were distinguished (D. awaricus, D. acicularis, D. andrzejejowskianus, D. × allwoodii, D. plumaris subsp. lumnitzeri, D. plumaris). D. × allwoodii and D. plumaris subsp. lumnitzeri are distinguished by the formation of growing clumps, which is important in ornamental horticulture and landscaping. On a 100-point scale, D. plumaris subsp. lumnitzeri scored 90 points, as well as 3 introduced species D. × allwoodii, D. carthusianorum L. (1), plumaris and 1 local white-flowered species D. awaricus awaricus scored more than 80 points, which are promising for use in ornamental horticulture .
