California Lilacs, or Ceanothus, are some of our most fragrant and colorful shrubs here in California. They are also evergreen and very drought tolerant. The myth of Ceanothus being short-lived is primarily spread by incompetent gardeners that insist on drip irrigation, summer water and soil amendments. Drought tolerant California native plants hate all three (except irrigation the first summer). Expect a 20-25 year life from your Ceanothus in most gardens. We have many Mountain Lilacs in the ground here that still look good after thirty years.
