Native Habitat:
Riparian areas, streambanks, forest edges, and open woodlands throughout western North America, including the Willamette Valley. Prefers moist, well-drained soils.
 
Bloom Time:
June – September
 
Growth Habit & Mature Size:
Perennial woody vine, climbing 10–20 feet, with compound leaves and clusters of small, fragrant white flowers. Produces elongated seed heads with feathery plumes in fall.
 
Light & Soil Requirements:
Full sun to partial shade; prefers moist, fertile, well-drained soils but tolerates a range of moisture conditions along streams and slopes.
 
Willamette Valley Native Companion Plants:
Cornus sericea, Ribes sanguineum, Salix spp., Mahonia aquifolium, Camassia quamash.
 
Urban Garden Function:
Adds vertical interest, seasonal flowers, and visual drama to urban riparian gardens, fences, trellises, and naturalized slopes. Its climbing habit can screen walls or structures while blending into woodland plantings. Ideal for habitat gardens, wildlife corridors, and mixed native plantings along urban streams or greenways.
 
Wildlife Supported:
Flowers attract native bees, butterflies, and hummingbirds. Seed plumes provide material for nesting birds. Dense vines offer shelter and nesting habitat for small birds and invertebrates.
