Native Habitat:
Moist forests, streambanks, floodplains, and shaded ravines throughout the Pacific Northwest, including the Willamette Valley. 
 
Bloom Time:
April – June
 
Growth Habit & Mature Size:
Deciduous shrub, 3–9 feet tall, with large, maple-like leaves and stout, upright stems. Produces long, drooping clusters of greenish-white flowers, followed by black, seedy berries. Leaves emit a distinct odor when crushed.
 
Light & Soil Requirements:
Partial to full shade; thrives in moist, humus-rich, well-drained soils. Prefers consistently damp sites, especially along streams or in forested wetlands.
 
Willamette Valley Native Companion Plants:
Tolmiea menziesii, Polystichum munitum, Athyrium filix-femina, Cornus sericea, Oemleria cerasiformis.
 
Urban Garden Function:
Provides lush foliage, seasonal flowers, and habitat structure in moist, shaded urban gardens, riparian plantings, and woodland restorations. Ideal for filling large understory spaces, stabilizing streambanks, and creating cool, shaded habitat pockets.
 
Wildlife Supported:
Flowers attract native bees and small pollinators. Berries are eaten by birds and small mammals. Dense, upright stems offer nesting habitat and shelter for wildlife.
 
Historical Use:
Berries were consumed sparingly by Indigenous peoples; stems and leaves used medicinally. Today valued primarily for ecological restoration, riparian function, and wildlife support.
