Flowering time dictates when Ceanothus should be pruned. Those that flower in late summer and early autumn are pruned in spring. Those which flower in spring and up to mid-summer are best pruned just after flowering. Never prune back into old bare wood.

Ceanothus, commonly known as California lilac, is a genus of evergreen and deciduous shrubs and small trees native to North America, particularly the western United States and Mexico. They are popular ornamental plants due to their showy flowers, attractive foliage, and ability to attract pollinators.
Ceanothus have small, dark green leaves that are often fragrant when crushed. The shrubs produce clusters of small, star-shaped flowers in shades of blue, purple, pink, and white in the spring and early summer. The flowers are highly attractive to bees and butterflies, making them a popular choice for pollinator gardens. Ceanothus can range in size from 1 to 20 feet tall and wide, depending on the species and growing conditions.
Ceanothus are relatively easy to grow and care for, making them a popular choice for gardens and landscapes. They prefer well-drained soil and full sun, although some species can tolerate partial shade. Ceanothus are drought-tolerant once established, but may require supplemental watering during dry spells. Pruning is usually not necessary, but can be done in late winter or early spring to maintain shape and size.
Ceanothus are often used in landscaping as hedges, screens, or as a specimen plant. Their showy flowers and attractive foliage make them an excellent addition to any garden. They are also used in erosion control, as their deep root systems can help stabilize soil on steep slopes. In addition to their ornamental uses, some species of Ceanothus have medicinal properties and are used in traditional medicine to treat a variety of ailments, such as respiratory infections and skin conditions.
Ceanothus are a beautiful and functional addition to any garden or landscape. With their attractive foliage, showy flowers, and ability to attract pollinators, they are a popular choice for both ornamental and ecological purposes.
