Ecological Indicator Information

A shade-tolerant/intolerant, montane, transcontinental North American forb (absent from the Pacific region). Occurs in continental montane boreal and cool temperate climates on fresh to very moist, nitrogen-rich soils. Scattered to plentiful in continental forests (persists in clearings); sporadic on water-shedding and water-receiving sites in the coast-interior ecotone. Often associated with Disporum hooken, Gymnocarpium dryopteris, Oplopanax horridus, Smilacina racemosa, and S. stellata. A nitrophytic species characteristic of Moder and Mull humus forms.
