Ceanothus are great additions to the habitat garden offering food and cover for birds and nectar for bees and butterflies.
Ceanothus hearstiorum
A rare species with limited distribution in San Luis Obispo County. One of the lowest of the ceanothus, up to 12 inches tall and about 6 ft. wide. Often completely flat with a star-like pattern of growth. Medium-blue flowers sit atop the narrow, wrinkled leaves in spring. Sun to light shade. More shade tolerant than most Ceanothus, making it a suitable option for under the dappled shade of oaks. Drought tolerant but will accept occasional irrigation. Excessive irrigation will shorten the life of this species. Provide good drainage.
Ceanothus incanus
A common and widespread Ceanothus found in the coast ranges of northern California but rarely cultivated in gardens. Probably best suited to conditions similar to where it would be found in the wild. Sunny slopes, canyons, the dappled shade in woodlands, with decent drainage, no to little summer water and full sun to light shade. Growing 5-10 ft. tall with arching rigid branches, whitish bark, stout twiggy spines and evergreen oval leaves of grey-green. Plumes of fragrant white flowers in the spring attract a wide array of insects, birds and butterflies.
Ceanothus integerrimus

Ceanothus maritimus ‘Point Sierra’
An excellent choice for a small scale ground cover, this rare Ceanothus is found on coastal bluffs and low hills in northern San Luis Obsipo County. Even though it is native to the coast it does surprisingly well inland. Smaller and slower growing than most Ceanothus, it blooms very early often beginning in late January or early February. 'Point Sierra' was selected from Arroyo de la Cruz by Native Son's Nursery. Grows 2-3 ft. tall with small, thick, leathery leaves and a dense mounding habit looking almost like Cotoneaster. Rounded clusters of blue-violet flowers from dusty white buds in late winter provide an early nectar source for pollinators of all sorts. A natural for coastal areas in full sun but has proven durable inland when it is provided a little shade. Tolerates heavy soils. Drought tolerant once established. Somewhat deer resistant.
Ceanothus maritimus ‘Popcorn’
A special white-flowered form of a very rare species from Hearst Castle in San Luis Obispo County. This rugged groundcover ceanothus reaches up to 3 ft tall and spreads to 5 ft wide, an excellent candidate for parkway strips and drier borders. The thick, rigid leaves are serrated along the margins and colored a pleasing gray-green. In spite of its coastal origin, 'Popcorn' tolerates sun and heat quite well, but will enjoy a little afternoon shade in the hottest interior locations. It has been long-lived and very drought tolerant here in Fulton, even putting up with our heavy clay soil. A fabulous pollinator plant which also provides food and cover for birds.
Ceanothus maritimus ‘Valley Violet’
Valley Violet ceanothus is a tough and reliable shrub introduced by the UC Davis Arboretum as an "Arboretum All-Star", one of their 100 top recommended plants. This relatively small Ceanothus grows 2 ft. tall by 4 ft. wide with small leathery leaves and gorgeous dark-violet flowers in early spring.

Drought tolerant once established. For a Ceanothus it is slower growing and has proven to be long lived and tolerant of many soil types. A wide array of pollinators are attracted to its flowers. Deer resistant.
Ceanothus papillosus – upright Baja form
This cold hardy selection from Baja California is highly useful in the garden setting thanks to its tall, upright form and narrow, vaselike shape. Many customers ask us for a big but narrow form of ceanothus. This is one of the few selections that fits the bill. Plants reach 8 – 10 ft tall, but only reach 3 – 4 ft wide, making it ideal for a privacy screen in a small area. Indigo blue flowers cover plants in spring, followed by little seed capsules which are relished by birds. The crinkly, dark-green leaves are elongated and create a nice foil for brighter green plants, such as Salvia and Artemisia. As with all ceanothus, the flowers are loved by a large array of pollinators. Plant in full sun to very light shade and water infrequently once established. Needs decent drainage. This is the variety papillosus.
