Ecological Indicator Information

Shade-tolerant/intolerant, submontane to montane, Pacific North American grass; occurrence decreases with increasing elevation and continentality. Species occurs in maritime to submaritime cool mesothermal climates on fresh to very moist, nitrogen-rich soils. Scattered in coniferous forests, more frequent in broad-leaved forests on water­receiving (floodplain and seepage) sites. Frequently associated with Galium triflorum, Polystichum munitum, and Tiarella trifoliata. Nitrophytic species characteristic of Moder and Mull humus forms.
