A shade-tolerant, submontane to subalpine, transcontinental North American forb. Occurs on fresh to very moist, nitrogen-rich soils within boreal, cool temperate, and cool mesothermal climates. Its occurrence increases with increasing precipitation and continentality. Occasional in broad-leaved forests on water-receiving (alluvial, floodplain, seepage, and stream-edge) sites. A nitrophytic species characteristic of Moder and Mull humus forms.
