A shade-intolerant, submontane to alpine, Western North American forb distributed more in the Pacific than the Cordilleran region. Occurs in water-shedding sites within alpine, tundra, boreal, cool temperate, and cool mesothermal climates. Common but scattered in non-forested communities and open-canopy forests. Usually inhabits very shallow soils on rocks subjected to severe desiccation but often affected by temporary surface seepage. Frequently associated with Pleurozium schreberi, Rhacomitrium canescens, and lichens. Characteristic of early-seral communities.
