Native Habitat:
Moist meadows, open woodlands, and prairie edges throughout western North America, including the Willamette Valley. Often found in seasonally wet soils or spring-flooded meadows.
 
Bloom Time:
April – June
 
Growth Habit & Mature Size:
Perennial bulb, 2–5 feet tall, producing erect flower spikes topped with dense clusters of star-shaped blue to violet flowers. Forms clumps over time.
 
Light & Soil Requirements:
Full sun to partial shade; prefers moist, well-drained soils. Tolerates seasonal wetness but does not thrive in heavy, poorly drained soils.
 
Willamette Valley Native Companion Plants:
Eriophyllum lanatum, Achillea millefolium, Sidalcea campestris, Festuca roemeri, Camassia quamash.
 
Urban Garden Function:
Provides striking spring blooms and vertical structure in urban meadows, pollinator gardens, and naturalistic landscapes. Excellent for mass plantings along pathways, in community gardens, or in seasonal wet areas. Its vibrant blue flowers add color contrast to green foliage and attract visual attention in layered native plantings.
 
Wildlife Supported:
Flowers attract native bees, bumblebees (Bombus spp.), and hummingbirds. Bulbs provide limited foraging for small wildlife, while the dense foliage offers shelter for insects.
 
Historical Use:
Bulbs were a staple food for Indigenous peoples, often baked or pit-cooked, and used ceremonially.
