Ecological Indicator Information

Shade-intolerant, submontane to montane, Western North American forb distributed more in the Pacific than the Cordilleran region. Species occurs in maritime to submaritime summer-dry cool mesothermal climates on moderately dry to fresh, nitrogen­rich soils (Moder and Mull humus forms). Scattered to plentiful in open-canopy Garry oak stands on water-shedding sites; occurrence decreases with increasing elevation and precipitation. Also inhabits meadow­like communities where early spring moisture is followed by mid-summer drought; occasionally found around vernal pools, springs, and intermittent streams.
