California’s Wild Lilacs

California Lilacs, or Ceanothus, are some of our most fragrant and colorful native shrubs. Evergreen and very drought tolerant, they provide us with ground covers, shrubs and small trees for various landscape situations. About 40 species are native to California, with many selected varieties also developed.

Many wild lilacs prefer coastal slopes but some are well-adapted to inland conditions. They all like well-drained soil, and prefer light watering and little or no fertilizing. Plants often work best in perimeter areas, on slopes and as background masses.

Ceanothus are fast-growing plants. This makes them useful for quick effects and covering large areas.

They begin blooming at an early age and cover themselves with beautiful, fragrant blossoms in the springtime. Flower colors include white, pale blue, deep blue and purple. Many small flowers are arranged like small lilac blooms at the end of the branches.

Ground cover Ceanothus do best in coastal areas, but some varieties will grow in inland conditions. ‘Yankee Point’ is a wide-spreading, low, dense shrub with shiny, dark green leaves and one-inch clusters of medium blue flowers. It is drought and heat tolerant.

Wild lilac shrubs grow anywhere from 3 feet to 16 feet tall. Most types are wider than they are tall. Many varieties grow well inland including ‘Dark Star’, ‘Julia Phelps’ and ‘Concha’ with deep blue flowers, ‘Frosty Blue’, with light blue blossoms, and ‘Joyce Coulter’, with large clusters of medium blue flowers. ‘Snowball’, with white flowers, also does well here.

‘Ray Hartman’ grows as a large shrub or small tree with large, glossy leaves and profuse displays of medium blue flowers. Sometimes they are grown as patio trees making a very showy display in spring.

Ceanothus grow best with little attention or care. Three things that they dislike are soil amendments, summer water and drip irrigation. Just water occasionally with a hose until the plants are established, then leave them to grow on their own. They will live a long and healthy life this way.

Deer-resistance is often an issue with Ceanothus. Most varieties are eaten by deer since, being natives, they have long been part of their food supply. Some small-leaved or prickly-leaved varieties, like ‘Dark Star’, ‘Julia Phelps’ and ‘Blue Jeans’, are usually more deer-resistant. But given protection when the plants are young, they are vigorous enough that they can withstand some browsing once they get large.

Wild lilacs are a nice addition to the natural landscape and they will delight you each spring with their wonderful, fragrant sprays of flowers.
