The article presents the results of the introduction study of Tall Bearded group of the Iris x hybrida hort. cultivars collection of Cheboksary branch of the MBG RAS for the purpose of determining the most promising for complex of biological features and adaptive capabilities during introduction in the soil and climatic conditions of the Middle Volga region. The potential possibilities of cultivars as an object for landscaping has been investigated. The determination of decorative qualities made it possible to divide the cultivars of iris into groups by color and size of the flower, to establish the number of flowers in an inflorescence, the height of the peduncle, the length of the leaf. As a result of the study of economic and biological characteristics, cultivars with a high, medium, low coefficient of vegetative reproduction, high, medium, low winter hardiness, moderately resistant very and moderately susceptible to heterosporous were identified. The study of the rhythm of seasonal development made it possible to determine the timing and duration of flowering of the studied cultivars of Iris x hybrida hort. in the conditions of the region. The main directions of further work with the collection are outlined.
