Monterey ceanothus. Grows 4’ tall and spreads to 10’ wide. A dense, mounding shrub with white puffs of flowers in early spring, this Ceanothus is best adapted to coastal locations in well-drained soil but can take heat and drought, as well as heavier soils. Mature plants tend to be woody and are best used as background subjects or replanted every 3 to 5 years. Hardy to 10F. Central California.
