CLIMATE
The climate type for this species, as reported in the "British Columbia plant species codes and selected attributes. Version 5 Database"(Meidinger et al. 2004), is not evaluated, unknown or variable.

ECOLOGICAL INDICATOR INFORMATION
A shade-tolerant, submontane to subalpine, circumpolar fem (transcontinental in North America). Occurs on fresh to very moist, nitrogen-rich soils within boreal, cool temperate, and cool mesothermal climates. Its occurrence increases with increasing precipitation, latitude, and continentality, and decreases with increasing temperature. Scattered to plentiful in forests on water-receiving (floodplain, seepage, and stream-edge) sites. Often associated with Athyrium filix­femina, Oplopanax honidus, Streptopus roseus, and Tiarella unifoliata. Characteristic of Moder and Mull humus forms.
