Ecological Indicator Information

A shade-tolerant/intolerant, montane to subalpine, Western North American forb disĀ­tributed equally in the Pacific and Cordilleran regions. Occurs on fresh to very moist, nitrogen-rich soils within subalpine boreal, temperate, and cool mesothermal climates; its occurrence decreases with increasing elevation. Scattered in broad-leaved forests on flooded sites, often inhabits exposed mineral soils in early-seral communities on water-receiving sites. A nitrophytic species characteristic of Moder and Mull humus forms.
