According to FNA: 'Androsace septentrionalis is broadly distributed and ruderal, occurring from low elevations at high latitudes to the alpine tundra in the Rocky Mountains. It is the most common species of Androsace across western North America and is variable in morphology, depending on elevation, exposure, and light. This plasticity has resulted in a plethora of infraspecific names. Most infraspecific taxa show little geographic coherence, and variants representing all the infraspecific taxa can be found throughout the range of this species, sometimes mixed within single populations.'
Native to Europe and SW Asia. Introduced as a forage and cover crop. Seems to have been used in reveg sites around the Tahoe Basin. Occasionally naturalized in the western U.S.
