California lilac
A very useful medium sized mounding evergreen groundcover discovered in 1956 by John Coulter. Grows 3 - 5 ft. tall and spreads 12 ft. or more wide. Medium-blue flowers cover this shrub in spring. Tolerates garden conditions better than most Ceanothus. Responds well to shearing and can easily be kept to a more compact size. Plant in full sun where it is drought tolerant but best with some summer water in hot interior sites. Shrubby ceanothus provide seeds eaten by bushtits, mockingbirds, quail and finches, as well as cover for birds.
