In the south of the Magadan region, Rhodiola whole-leaved (R. integrifolia) is found. This species is the most hardy, dry-loving and decorative. The seed pods look no less impressive than the flowers. The plant also thrives in Estonia.

Location: prefers a sunny location
Soil: requires well-drained, nutritious soil. During the growth period they are moisture-loving; after flowering, waterlogging is unacceptable.
Reproduction: by seeds and division of rhizomes. The seeds are very small, so growing seedlings is difficult and is only possible in protected soil. 1.0 g = 7050 seeds.
Seedlings are not capricious, but require sufficient lighting and even, moderate watering. Flowering occurs 3-4 years after sowing. Vegetative propagation is easy by division and cuttings of growing shoots in the spring. They live in one place without transplantation for a long time, but they tolerate it easily.
Use: an exceptionally elegant plant, looks especially impressive among gray and reddish stones.
