Genus guide
Ceanothus — 10 species
Ceanothus, commonly called California lilac, is a genus of mostly fast-growing evergreen shrubs and groundcovers native to western North America, beloved for their profuse clusters of blue, violet, or white flowers in spring. Cultivars like 'Concha', 'Victoria', and Ceanothus thyrsiflorus 'Skylark' excel in full sun and sharply drained soil, and are notably drought-tolerant once established — deep, infrequent watering suits them far better than regular irrigation. All Ceanothus species are considered toxic to cats and dogs, so keep them out of reach of pets.

Ceanothus — frequently asked questions
Are Ceanothus plants toxic to cats and dogs?
Most Ceanothus are not pet-safe. Of the 10 Ceanothus species in the Growli library, 10 (100%) carry a toxic or mildly-toxic ASPCA classification and 0 are pet-safe. Always confirm the exact species on its pet-safety page before trusting it around cats or dogs.
How much light do Ceanothus plants need?
Most Ceanothus do best in direct sun. If yours stretches toward the window or loses its variegation it wants more light; scorched or bleached leaves mean it is getting too much direct sun.
Are Ceanothus easy to care for?
Some Ceanothus suit more experienced growers — several want strong light, sharp drainage or a specific seasonal rhythm. Check the individual species page for the exact regime.
