Ecological Indicator Information

A shade-intolerant. submontane to subalpine. transcontinental North American deciduous shrub. Occurs in continental cool temperate and cool semiarid climates on moderately dry to fresh. nitrogenĀ­rich (occasionally weakly alkaline) soils (Moder and Mull humus forms). Its occurrence increases with increasing temperature and continentality. and decreases with increasing precipitation and latitude. Occasional in immature broadĀ­leaf forests on water-shedding sites on leeward Vancouver Island and in the coast -interior ecotone. A nitrophytic species characteristic of young-seral, continental forests.
