Ecological Indicator Information

A shade-tolerant/intolerant, submontane to montane, Asian and Western North American forb distributed more in the Pacific than the Cordilleran region. Occurs in cool temperate and cool mesothermal climates on wet to very wet, nitrogen-rich soils (Moder and Mull humus forms): its occurrence decreases with increasing elevation and continentality. Common in open-canopy red alder, Sitka spruce, and western redcedar stands on water-collecting sites with gleysolic or organic soils. Often associated with Athyrium filix-femina and Lysichitum americanum. Inhabits depressions with a surface groundwater table. A nitrophytic species characteristic of nutrient-rich wetlands.
