Ecological Indicator Information

A very shade-intolerant, submontane to subĀ­alpine, Western North American forb distributed more in the Pacific than the Cordilleran region. Occurs in maritime to submaritime summer-dry cool mesothermal climates on excessively dry to very dry, nitrogem-poor soils; its occurrence decreases with increasing precipitation and continentality. Sparse to sporadic in non-forested communities on very shallow, water-shedding sites (rock outcrops and cliffs). Characteristic of moisture-deficient sites.
