Shade-tolerant/intolerant, sub montane to montane, Pacific North American forb. Occurs in cool mesothermal climates on very moist to wet, nitrogen-rich soils. Occurrence decreases with increasing latitude, elevation, and continentality. Sporadic in the herbaceous understory of broad-leaved forests on water-receiving (floodplain) sites. Commonly associated with Adiantum pedatum, Athyrium filix-femina, Circaea pacifica, Oplopanax horridus, Tiarella trifoliata, and Tolmiea menziesii. A nitrophytic species characteristic of Moder and Mull humus forms.
