Ecological Indicator Information

A shade-intolerant, submontane to montane. Western North American forb distributed more in the Pacific than the Cordilleran region. Occurs in cool mesothermal climates on very dry to moderately dry, nitrogen-poor soils (Mor humus forms). Sporadic in open-canopy forests on strongly drained, rocky and stony, water-shedding sites; also in non-forested communities on disturbed sites. An oxylophytic species characteristic of moisture-deficient sites.
