Julia Phelps ceanothus is densely branched evergreen shrub that develops into a large mounded shape, 7-9 ft. tall, 10-12 ft. across. Tiny dark green leaves grow to 1/2 in. long and are heavily wrinkled. Numerous dark purple-blue flowers in 1 in. rounded clusters cover the plant for a showy display in mid spring.
Julia Phelps ceanothus is another of the large shrub-type ceanothus cultivars that grow well with other natives in drought tolerant gardens. Due to its large size, tiny foliage and stiff branching habit this plant is well suited for background, screen and slope planting purposes. This cultivar needs sun, well drained soils and careful summer watering when grown in residential gardens.
