Roseroots

Rhodiola is a genus of perennial plants in the family Crassulaceae that resemble Sedum and other members of the family. Like sedums, Rhodiola species are often called stonecrops. Some authors merge Rhodiola into Sedum.

Rhodiola species grow in high-altitude and other cold regions of the Northern Hemisphere. Plants of the World Online gives the number of accepted species as 74, the Angiosperm Phylogeny Website gives it as 90, and the Flora of China gives it as about 90, with 55 in China and 16 endemic there. Flora of North America lists only three species in the United States and Canada.
