There are more than 100 species of Androsace, distributed in temperate regions of the northern hemisphere, mainly in Eurasia. The USSR has about 35 species, growing mainly in the arctic and in the subalpine and alpine zones of mountains. A. septentrionalis grows in arid meadows and on dry slopes in forest and forest-steppe zones. A. filiformis is found mainly in the forest zone in moist shady places, often along forest paths. Some high-altitude and arctic species form dense covers. Several species, such as A. carnea, A. villosa, and A. sarmentosa, are raised as ornamentals.
