The Wartleaf Ceanothus is grown for its showy flowers and rounded bushy habit. It is planted around buildings or along borders as a low screen. It is also grown in tubs and planter boxes and is excellent for coastal regions. It is used in rocky hill side gardens and establishes in 1 to 2 years but is short lived in warm wet areas. ID 832
