Lupinus rivularis
Streambank Lupine is a perennial native wildflower found in coastal prairies, open woodlands, riverbanks, and disturbed habitats throughout the Pacific Northwest and western North America. Its upright stems hold showy clusters of blue to purple, pea-like flowers that bloom from spring into summer and attract native bees, butterflies, and other pollinators. Its deep roots help it tolerate dry conditions once established, while its seeds allow it to readily colonize open ground.
Soil Type: Well-drained, sandy, gravelly
