This low growing Ceanothus has bright, cobalt-blue flowers and small dark-green, shiny leaves. Spreads quickly to around one foot tall by 6 - 8 feet wide. The flowers are displayed in profusions of small pom-poms colored an intense deep-blue set above small glossy foliage. Drought tolerant but will tolerate moderate irrigation in faster draining soils. More shade tolerant than many Ceanothus but will take full sun except in hot, inland areas. Selected by Roger Raiche at Horseshoe Cove, Sonoma County.
A natural cross between Ceanothus foliosus and C. thyrsiflorus var. griseus.
