Description: Rhodiola roseaSN|34514]]SN|34514]] is a glabrous perennial succulent herb growing from 5 to 40 cm tall, and has several stems growing from a short, scaly rootstock. Flowers have 4 sepals and 4 petals, yellow to greenish yellow in colour sometimes tipped with red, about 1 to 3.5 millimetres long, and blooming in summer. Plants are mostly dioecious (individual flowers are either male or female, but only one sex is to be found on any one plant so both male and female plants must be grown if seed is required).
Rootstock: Erect or spreading, 5-25 mm in diameter. The root exhales the odour of the rose
Stems: Floral stems branched at the base, or simple, erect or ascending, glabrous and somewhat glaucous, deciduous growing from the same thick root may reach 5 to 40 cm in height and 2-6 mm in diameter.
Leaves: Sessile. Blades pale green, usually glaucous, ovate to or slightly obovate or oblong, margins toothed or sometimes almost entire, apex acute to obtuse, narrowed or rounded at the base, 10-50 mm long 4-15 mm wide, the lower ones smaller.
Inflorescences : Terminal. The numerous flowers (up to 150) are nearly sessile, crowded in a dense corymbose cyme, to 6.5 cm in diameter. Pedicels ca. 3 mm long.
Flowers: Yellowish-green or purplish. Mostly unisexual (dioecious), buy occasional plants may have both staminate and pistillate flowers in the same cyme. Flowers are 4(-5)-merous. Sepals linear-oblong or lanceolate, narrower and shorter than the petals, unequal, 1-2.5 mm long. Petals pale yellow to greenish yellow, sometimes red at tips, oblong, 1-3.5 mm long, shorter than stamens, in staminate flowers spreading, hooded, 0.7-1.1 mm wide, in pistillate erect. Staminate flowers with 8 (rarely 10) stamens, the pistillate ones with 4 (rarely 5) carpels. The plant is not self-fertile.
Fruits (follicles): 4-9 mm long; beaks spreading.
Seeds: Reddish brown to purple, winged at both ends, pyriform, 1.7-2.2 mm long and 0.5-0.7 mm wide. The seeds form capsules during the second half of the summer. Under natural conditions, the ripened seeds fall in August and September.
Chromosome number: 2n = 22.
Remarks: Linnaeus used the epithet "Rosea" as a feminine noun (does not decline with the gender of the genus).

Cultivation and Propagation: Rhodiola rosea is for both light (sandy), medium (loamy) and heavy (clay) soils and prefers well-drained soil. It is suitable for acid, neutral and basic (alkaline) soils.
It cannot grow in the shade. It is partially drought tolerant, salt tolerant, and wind tolerant.
Food uses. The leaves and shoots are eaten raw, having a bitter flavour, or cooked like spinach, and are sometimes added to salads.
Traditional medicine: Historically, people in northern regions have used rhodiola for anxiety, fatigue, anemia, impotence, infections, headache, and depression related to stress. People also have used it to increase physical endurance, work performance, longevity, and improve resistance to high-altitude sickness. Through 2012, human studies evaluating R. rosea did not have sufficient quality to determine whether it has properties affecting fatigue or any other condition.
