General:
Deciduous, erect, large shrub, 1-6 m tall; twigs thick, soft, pithy, usually somewhat glaucous; bark dark reddish-brown, warty.
Leaves:
Opposite, stalked, large, compound, pinnately divided into 5-7 elliptic to lanceolate leaflets, often asymmetric at the base, abruptly sharp-pointed at the tip, saw-toothed on the margins, and usually somewhat hairy beneath.
Flowers:
Inflorescence of numerous, small flowers in a 4-10 cm long, egg-shaped to conical cluster with short lateral branches on a stronger central axis; corollas white or cream, wheel-shaped; petals fused at base into a short flat tube that spreads (3-6 mm across) at the top to 5 lobes, the lobes longer than the tubes and becoming reflexed.
Fruits:
Berrylike, globose, 5-6 mm across, shiny red or purplish-black, occasionally brown, yellow, or whitish, but not glaucous, with 3 small, smooth to wrinkled or pebbled stones, each enclosing a seed.
Notes:
Three varieties of this North American subspecies occur in BC. Fruits black or purplish-black; nutlets slightly wrinkled or pebbly var. melanocarpa (A. Gray) McMinn. Fruits bright red (sometimes yellow or white); nutlets mostly smooth or slightly wrinkled or pebbly. Nutlets mostly smooth; plants 2-6 m tall var. arborescens (T.& G.) A. Gray. Nutlets slightly wrinkled or pebbly; plants 0.5-3 m tall

Ecological Indicator Information

A shade-tolerant to shade-tolerant/intolerant, sub montane to subalpine, circumpolar deciduous shrub (transcontinental in North America). Occurs on fresh to very moist, nitrogen-rich soils within boreal, temperate, and cool mesothermal climates; its occurrence decreases with increasing elevation. Scattered to plentiful in open-canopy forests on water-receiving sites. Indicative of rapid decomposition of forest floor materials (originally Mor humus forms) remaining on cutover or fire-disturbed, water-shedding sites. Usually associated with Alnus rubra, Athyrium filix-femina, Epilobium angustifolium, Rubus parviflorus, and R. spectabilis. A nitrophytic species characteristic of Moder and Mull humus forms.
