Native Habitat:
Open forests, forest edges, and rocky slopes in western North America, including the Willamette Valley foothills. Often found in well-drained soils and disturbed areas.
 
Bloom Time:
May – July
 
Growth Habit & Mature Size:
Deciduous to semi-evergreen shrub, typically 3–6 feet tall, with slender reddish stems and dark green leaves. Produces clusters of white flowers in late spring to early summer.
 
Light & Soil Requirements:
Full sun; prefers well-drained soils, including rocky or sandy substrates. Tolerant of drought once established.
 
Willamette Valley Native Companion Plants:
Arctostaphylos columbiana, Festuca roemeri, Camassia quamash, Achillea millefolium, Eriophyllum lanatum.
 
Urban Garden Function:
Adds seasonal color, structure, and texture to urban habitat gardens, slopes, and naturalized landscapes. Its delicate white flower clusters contrast with red stems, providing visual interest in spring. Works well in layered plantings with other native shrubs and perennials, and serves as a low-maintenance focal or filler plant in sustainable urban landscapes.
 
Wildlife Supported:
Flowers attract native bees (Bombus spp., Osmia spp.), butterflies, and other pollinators. Dense branching provides shelter and nesting opportunities for small birds and insects.
 
Historical Use:
Used by Indigenous peoples for medicinal purposes, dye, and occasionally for basketry.
