ABSTRACT: The study of flowering biology is an important stage in the process of plant introduction, as it allows assessment of the degree of tolerance to environmental factors and provides recommendations for large-scale cultivation of introduced plant species. R. tinctorum is a perennial herb reaching 30 - 150 cm in height. The rhizome is elongated, creeping, branched, cylindrical, thick, nodular, and polycephalous. The stem is multiple, quadrangular, nodal, highly branched, and covered with rough hooked hairs. Medicinal preparations derived from its rhizome are used in the treatment of urinary calculi, kidney stones, gallstones, and gout, while in the textile industry the plant serves as a valuable dyeing raw material.
