Relevance. For the first time as a result of the research work carried out to study the acclimatization and adaptive features of shade-tolerant plants an assortment of ornamental and resistant herbaceous perennials for the Stavropol region, used for landscaping shady areas, has been proposed.Methodology. Fundamentals of plant introduction, Karpun, 2016; Mеthods of phenological observations in botanical gardens, GBS, 1975; Biological features of ornamental plants of natural flora in Western Siberia, Fomina, 2012; Evaluation of successful introduction according to visual observations, Karpisonova, 1978. The species names of the studied plants were specified according to Cherepanov, 1995 and the Internet resource.Results. Research work on the study of indicators characterizing the group of shadetolerant herbaceous perennials, both from a scientific and practical point of view, was carried out during 2017–2021. Long dry period 2018–2020 in the Stavropol Territory had a negative impact on the general condition of shade-loving plants. The most droughtresistant species were established. Еxtreme weather conditions did not affect their vital signs, the plants looked normally developed, healthy, bloomed profusely, actively fruited. As a result of scientific research it was found that most of the studied perennials belong to semi-shade-tolerant plants, spring-summer-autumn green phenorhythmotype — vegetative from early spring to late autumn. The difference in height of plants and decorative features allows to distribute them into different types of flower beds on gardening areas. One of the main tasks of the research work carried out is to expand the range and attract shade-loving ornamental perennials for gardening in Stavropol and other, more arid settlements of our region. Shade-tolerant species and cultivars are a good scientific basis for holding regional ecological seminars, consultations on agrotechnics of growing and distribution of plants in different parts of the shady garden.
