Overview
Rhodiola (Rhodiola rosea) is a succulent perennial in the stonecrop family (Crassulaceae), native to the cold, high-altitude and arctic regions of Europe, Asia and North America.
It is best known as an adaptogen — an herb traditionally used to help the body resist physical and mental stress and fatigue. Its thick rhizome, which smells of rose when cut (hence "rose root" and "golden root"), has a long history of use in Scandinavia, Russia and the Himalayas.
A tough survivor of harsh climates, rhodiola forms low rosettes of fleshy leaves and yellow flowers, thriving where few other medicinal plants can.
How to identify it
- Flowers: dense clusters of small yellow (sometimes greenish-yellow) flowers atop the stems in early summer; plants are usually dioecious (separate male and female)
- Leaves: fleshy, blue-green, oval to lance-shaped, succulent, densely set along the stems
- Stems: several upright stems, 5-35 cm tall, arising from a stout rootstock
- Root: thick, branching golden-fleshed rhizome that smells of rose when cut
- Habit: low, clumping alpine/arctic succulent
Care & growing
Light: Full sun; it is adapted to bright, exposed conditions.
Water: Low to moderate; the succulent leaves store water and the roots rot in soggy soil, so excellent drainage is essential.
Soil: Gritty, sharply drained, even rocky soil; tolerates poor, lean ground.
Temperature: Extremely cold-hardy (roughly USDA zones 2-7); it actually needs cold winters and struggles in hot, humid climates.
Feeding: Little to none; it is adapted to nutrient-poor soils.
Propagation: From seed (cold stratification needed) or division of the rhizome; roots are usually harvested after several years of growth.
Habitat & origin
Rhodiola rosea grows in cold mountain and arctic regions across the Northern Hemisphere, including the mountains of Europe, the Arctic, Siberia, Central Asia and parts of North America.
It favors rocky ledges, cliffs, alpine meadows and sea cliffs at high latitudes or elevations. Cultivation succeeds best in cool-climate gardens with gritty, well-drained soil; it is also grown commercially for the herbal-supplement trade.
Uses & benefits
Medicinal: The dried root is a widely used adaptogen, taken traditionally and in modern supplements to support energy, stamina and resistance to stress and fatigue.
Ornamental: A charming, tough rock-garden and alpine-trough plant with succulent foliage and yellow flowers.
Ecological: Flowers provide nectar to insects in harsh high-altitude environments.
Note: As with any supplement, consult a healthcare provider before regular use.
Frequently asked questions
What is rhodiola used for?
Its root is a traditional adaptogen taken to help the body cope with stress and fatigue and to support energy and mental stamina. Consult a healthcare provider before using supplements.
Why is it called golden root or rose root?
The thick rhizome has golden-colored flesh and gives off a rose-like fragrance when cut, which inspired both common names.
Can I grow rhodiola in a warm climate?
It is difficult in hot, humid areas because it is an arctic-alpine plant that needs cold winters, full sun and sharply drained, gritty soil to thrive.
How long until rhodiola roots can be harvested?
Roots are typically left to grow for several years (often four or five) before harvesting so they reach a useful size and potency.
