The table below shows the species-specific information calculated from original data (BEC database) provided by the BC Ministry of Forests and Range. (Updated August, 2008)
A shade-tolerant to very shade-intolerant, submontane to subalpine, Western North American herb distributed equally in the Pacific and Cordilleran regions. Occurs on very moist to wet, nitrogen-rich soils (Moder and Mull humus forms) within boreal, temperate, and cool mesothermal climates; its occurrence increases with increasing latitude and precipitation. Common in non-forested communities and open-canopy forests on water-receiving (flood-plains and stream-edge) sites. Usually associated with Athyrium filix-femina, Cornus sericea, Lysichitum americanum, Rubus spectabilis, and Tiarella trifoliata. A nitrophytic species characteristic of flooded sites.
