The Joyce Coulter ceanothus grows into a medium to large mounding to sprawling shrub, growing 4-5 ft. tall, spreading at least 10-12 ft. across. Dark green leaves grow 1 1/2 in. long by 1/2 in. wide and are heavily wrinkled. Long clusters of medium to light blue flowers develop provide a showy display in late winter to early spring.
Joyce Coulter ceanothus is well suited as a bank and background plant to cover large spaces and where it can provide handsome year around foliage color and colorful springtime flower value. It can be clipped as a hedge when planted in tight spaces. Like other varieties of Ceanothus, it grows most reliably in well-drained soils and with careful summer watering. In hot Inland Empire landscapes and gardens it maintains better foliage character when protected from hot afternoon sun.
