Ceanothus thyrsiflorus - California Lilac (5 Gallon)

About this item

Blueblossom, also known as California Lilac or Blue Brush, is a fast-growing, versatile evergreen native to the Pacific Coast. Celebrated for its abundant spring blooms and glossy green foliage, this beautiful shrub brings vibrant color and year-round interest to native gardens and naturalistic landscapes. Its fragrant clusters of blue to light blue flowers, occasionally appearing in white, create a spectacular display from spring into early summer.

Its glossy, dark green leaves feature three distinctive veins, while its sturdy green branches provide an attractive structure throughout the year. The nectar-rich blooms attract bees, butterflies, hummingbirds, and other beneficial pollinators, while its seed capsules provide food for birds and small mammals.

Adaptable to a variety of well-drained soils, Blueblossom thrives in sunny locations and tolerates partial shade. Once established, it is highly drought-tolerant and an excellent choice for water-wise gardens, wildlife habitats, and California-native landscapes. Avoid excessive summer watering, as this can shorten the plant's lifespan.
