What is California lilac?
California lilac is Ceanothus, a group of mostly evergreen shrubs and groundcovers known for intense blue flowers and low-water performance.

Is California lilac drought tolerant in California?
Yes. Once established, many Ceanothus varieties need little summer water, especially in well-drained soil and full sun.

Does California lilac stay evergreen?
Many popular garden varieties are evergreen, but some types can be semi-evergreen depending on cultivar and winter conditions.

How much sun does Ceanothus need?
Most perform best in full sun. Some coastal or woodland-edge selections can handle light afternoon shade.

When does California lilac bloom in the Bay Area?
Bloom time varies by variety, typically late winter through spring, with some extending into early summer.

How fast does California lilac grow?
Many grow quickly once established, especially in sun and well-drained soil, making them great for fast screening.

Can I use California lilac as a hedge?
Yes. Upright forms can be trained as informal hedges, but avoid heavy shearing; light shaping after bloom is best.

Does Ceanothus need fertilizer?
Usually no. Over-fertilizing can reduce flowering and make growth weak; focus on drainage and proper watering instead.

Is California lilac deer resistant?
It is often considered deer resistant, but no plant is deer proof; new growth may be browsed in high-pressure areas.

Why did my California lilac decline after summer watering?
Many Ceanothus dislike frequent summer irrigation once established and can develop root issues. Deep, infrequent watering is safer, or keep it mostly dry.
