A vigorous California native shrub with deep blue flower clusters in spring and attractive evergreen foliage. Extremely drought-tolerant once established and excellent for water-wise gardens.
Why grow it
Ray Hartman Ceanothus is a larger cultivar (8-12 feet) compared to many other California lilacs, making it suitable for screen plantings or as a structural element in drought-tolerant landscapes. It flowers reliably in spring with dense blue panicles and maintains foliage year-round, offering visual interest across seasons. Among Ceanothus varieties, this selection performs well in coastal and inland regions with full sun and established drought tolerance.
Watch out for
This cultivar prefers well-draining soil and may struggle in clay or consistently moist conditions. Young plants benefit from careful watering during establishment, typically their first season, though overwatering during this period can cause root rot. In cooler or more humid climates outside its native range, air circulation becomes important to prevent fungal issues.
