Baccharis pilularis ‘Twin Peaks’
One of the fastest, toughest, densest evergreen native large scale groundcovers. Discovered on Twin Peaks in San Francisco. Grows at least to 6 ft. wide and 2 - 3 ft. tall. Extremely drought tolerant along the coast but best with moderate to occasional summer water inland. Shear hard annually in spring to keep rejuvenated. Sun on coast, afternoon shade inland. This is a male selection so it won't produce seeds. Deer don’t seem to eat it.
Baccharis salicifolia
This native shrub looks something like a willow in foliage and is found in similar habitats in California and the southwest US. Not a willow at all, but a member of the aster family, this evergreen shrub blooms nearly year round, making it a powerhouse for pollinators. The profusion of small, creamy white, fuzzy flowers, tinged with pink or red are highly attractive to butterflies, bees and other beneficial insects. Extremely tough and easy to grow in full sun with summer water, where it will grow 6 - 10 feet tall and wide with rich, green foliage. Able to survive drier conditions than a willow could handle, but it will look rough if it gets too dry. Responds well to pruning and can be cut down to six inches to refresh. Excellent screen, windbreak and for soil stabilization. Stellar for attracting pollinators.
Berberis (Mahonia) aquifolium
This attractive, western native evergreen has a long history in cultivation for good reason. Erect stems rise 4 to 7 feet or more tall and wide, spreading slowly by underground rhizomes to form dense clumps. Bronzy-red new growth gives way to dark-green, glossy leaves with spiny margins that are prickly to the touch. Cold winters can darken the foliage with purple-red tones. Late spring brings clusters of bright yellow, sweetly scented flowers. Edible blue-black fruits follow and are pretty and tasty. A useful and adaptable shrub in a hedge or a shrubby border. Takes full sun to part shade. Performs best with some afternoon shade in hot areas and moderate to infrequent water. A great habitat plant which provides cover, nectar rich flowers and fruits relished by all. Deer resistant.
Berberis (Mahonia) aquifolium var. repens
This little cousin of the much larger Oregon grape only gets 1 - 3 ft. tall and spreads underground to create dense, evergreen drifts. The divided leaves have a matte finish with a grey-green color which turns purple-red with frost. Clusters of bright yellow flowers open in spring and are followed by deep blue "grapes" much loved by birds. The sweet-scented flowers are enjoyed by bees and butterflies. Provide full sun to shade and moderate to infrequent irrigation. Deer resistant.
Berberis (Mahonia) nervosa
A handsome species with especially long, leathery, evergreen leaves. Grows to around 2 or more feet tall and spreads by underground stems. Yellow flowers in spring are born in upright clusters, followed by blue berries. Great woodland groundcover for full or partial shade with occasional to regular summer water. Deer resistant. Fruits eaten by robins, finches and towhees. The flowers have nectar for hummingbirds and bees.
Berberis (Mahonia) nervosa var. mendocinoensis
The rare Mendocino longleaf mahonia comes from moist coniferous forests around Fort Bragg. Differs from the more diminutive longleaf mahonia in its unusual size: growing slowly to 5 ft tall or more and spreading to form narrow colonies. The pointed, leathery, deep green leaves, bronzy orange when young, provide a striking contrast to the bright yellow flower clusters produced in the spring. Attractive deep purple berries are a food source for birds. Needs shade and moderate moisture. Deer resistant.
Berberis (Mahonia) nevinii
Nevin's barberry is a very rare southern California shrub with rigidly arching stems densely clothed in pointy silver gray leaflets. Heavy blooming with clear yellow flowers followed by heavy fruiting with bright red translucent fruit. 8 ft. by 8 ft. Does well in sunny well drained locations in the Bay Area. Great companion to matilija poppy and Salvia clevelandii. Very drought tolerant but best with occasional water. Deer resistant.
Berberis (Mahonia) pinnata ‘Ken Hartman’
Similar to Oregon grape (Mahonia aquifolium) but leaves are more crinkly and spiny. New growth often shows lots of red and orange. Grows upright to 6 ft. or more, particularly in ideal coastal sites. Handles drought better than the Oregon grape. Tolerates sun to shade. Best with a little shade in hot areas. Fruits eaten by robins, finches and towhees. The flowers have nectar for hummingbirds and bees. Deer resistant.
Calliandra californica
Clusters of bright red flower filaments, resembling little dusters, adorn this Baja California native for much of the year. The dainty, fern-like leaves are generally evergreen, though they are less ubiquitous in the winter. This mid-sized shrub reaches up to about 5 ft tall over time and spreads to 5 ft wide, forming a loose, rounded mound. Hummingbirds and butterflies favor the flowers on this unusual member of the pea family. Hardy to around 25 degrees. Plant in full sun to light shade and provide occasional to no irrigation once established. Said to be tolerant of clay soils, but will not like flooding.
Calycanthus occidentalis
Native along streams, rivers and moist places in California. This attractive deciduous shrub is well worth growing. Bright green aromatic foliage with interesting maroon-red flowers in spring-summer that resemble small waterlilies and have a wine-like fragrance. Can be grown as a multi-stemmed small tree, trimmed hedge or left alone to become a large background shrub. 5 - 12 ft. tall and wide. Part-shade is ideal. Tolerates full sun with lots of moisture in somewhat cooler areas. Accepts full shade but will grow more slowly with a more open habit. Regular to moderate water. Somewhat deer resistant.
Carpenteria californica
Long in cultivation, this native, evergreen shrub is rare in the wild, with a limited distribution in their native habitat. Forms a multi-branched shrub, 5 - 7 foot tall or more and nearly as wide, with dark green, leathery, lanceolate shaped leaves, which provides a dark foil to the brilliant white flowers. Late spring brings terminal clusters of white, 2 -3 inch, sweetly scented, anemone-like blossoms with yellow centers. An adaptable shrub which makes a striking specimen or foundation plant in a woodland area with morning sun and afternoon shade. Responds well to pruning and can be trained as an espalier. Drought tolerant, but appreciates occasional summer water. Flowers enjoyed by bees and butterflies.
Carpenteria californica ‘Elizabeth’
A beautiful native evergreen shrub 5 - 7 ft. tall and 4 ft. or more wide. Blooms May-July with sweetly scented, pure white, yellow-stamened, camellia-like single flowers. This cultivar is especially free flowering with smaller than usual (2 inch) flowers in masses of up to 20 in each of the terminal clusters. Said to be more disease resistant. Has a narrow upright appearance which is unusual for a native shrub. Best with light shade or morning sun. Drought tolerant, but appearance is improved with some summer water. Does want decent drainage.
Ceanothus ‘Antonette’
An exciting introduction by Native Sons Nursery which was discovered in their landscape. ‘Antonette’ is believed to be a cross between Ceanothus arboreus and Ceanothus ‘Cynthia Postan’ with unusual elongated leaves which remind us of a rockrose. Grows 8 – 10 feet tall and 6 – 8 feet wide with spectacular displays of frosted, violet-blue flowers in early spring. Before they fully emerge, the flower buds display a pleasing rosy color. Plant in full sun with occasional to little summer water once established. Valuable habitat plant, providing food and cover for birds, bees and butterflies.
Ceanothus ‘Berkeley Skies’
A seedling selection from the Botanic Garden at UC Berkeley, thought to be a cross between Ceanothus megacarpus and Ceanothus gloriosus. Forms an upright shrub 8-15 ft. tall with small leathery leaves and stiff arching habit. The eye-catching flowers are soft lilac in color with a deep purple center eye to each flower. It comes into bloom quite early, often beginning in late January and February where they are much adored by bees in search of nectar. Ceanothus require decent drainage, full sun and are drought tolerant once established.
Ceanothus ‘Better Than Ray Hartman’
A friend of ours, Eric Nelson, discovered this spectacular selection growing on a property near where he lived. Masses of rich, blue-purple flowers held in large sprays cover the plant in spring, attracting bees and butterflies. The seeds which follow feed an array of birds. Reaches 10 – 15 ft. tall and wide with larger, deep-green, rounded leaves. We believe this plant is an existing cultivar, but none of the Ceanothus experts have been able to reach a consensus on exactly which one, hence the peculiar name referencing a selection which it resembles. Plant in full sun to light shade and water occasionally or less once established.
Ceanothus ‘Blue Jeans’
Not the color of denim exactly, the profuse springtime blossoms of 'Blue Jeans' are a rich lavender-purple. Erect evergreen shrub 6 ft. tall and wide with small shiny green leaves. Vigorous and fast growing. Best in full sun with little to no water once established. Tolerates heavy soils. Shrubby Ceanothus provide seeds eaten by bushtits, mockingbirds, quail and finches, as well as cover for birds.
Ceanothus ‘Blue Ray’
A Suncrest Nursery introduction, this is a cross between two popular cultivars, Ceanothus 'Ray Hartman' and Ceanothus 'Dark Star'. Grows 10 feet tall by 15 ft. wide with deep green textured leaves on sturdy stems forming a large mound. Deep vivid blue flowers in dense clusters cover the shrub in spring. Plant in full sun with occasional to no summer water once established. Ceanothus, when in flower, are highly attractive to pollinators of all sorts.
Ceanothus ‘Celestial Blue’
A beautiful hybrid California lilac selected and introduced by Las Pilitas Nursery. Luminous, rich blue flowers, in tight, conical clusters put on a massive display in spring with the added bonus of sporadic blooming through summer and into fall. Growing 6-8 ft. tall and wide with a mounding habit. Useful as an accent, informal hedge or screen shrub where it grows in full sun to light shade with little to no water once established. Ceanothus are an excellent addition to the habitat garden attracting a myriad of insects and birds.
Ceanothus ‘Centennial’
This low growing Ceanothus has bright, cobalt-blue flowers and small dark-green, shiny leaves. Spreads quickly to around one foot tall by 6 - 8 feet wide. The flowers are displayed in profusions of small pom-poms colored an intense deep-blue set above small glossy foliage. Drought tolerant but will tolerate moderate irrigation in faster draining soils. More shade tolerant than many Ceanothus but will take full sun except in hot, inland areas. Selected by Roger Raiche at Horseshoe Cove, Sonoma County.
Ceanothus ‘Concha’
An adaptable shrub growing 6 ft. tall and wide, with a dazzling display of glowing purple-blue flowers in the spring. The gracefully arching branches carry dark green shiny leaves and are tolerant of light pruning. Thrives in full sun with little or no water once established. More tolerant of heavy soils and summer watering than most ceanothus. Shrubby Ceanothus provide seeds eaten by bushtits, mockingbirds, quail and finches, as well as cover for birds.
Ceanothus ‘Coronado’
Phil van Soelen selected this striking natural hybrid from along the Sonoma Coast. It was named for the late David Coronado, our dear friend and a talented plantsmen. Compact habit growing to around 2 ft. tall and 6 ft. wide with dark green, deeply veined, toothed leaves. Frosty blue buds open to luminous deep blue blossoms in early spring. Perhaps best in somewhat cooler climates where it performs beautifully in full sun with moderate to no water once established. Ceanothus are excellent habitat plants providing cover and food for wildlife. The early flowers provide nectar for pollinators and seeds for birds. The myriad of insects attracted to the flowers are an added attraction to birds.
Ceanothus ‘Dark Star’
This popular small leaved shrub reaches 4 - 6 ft. high by 6 - 10 ft. wide. The electric cobalt-blue flowers cover the plant in spring and are very popular with bees and butterflies. Plant in full sun and provide decent drainage. Not a good choice for hot, inland areas. Drought tolerant. 'Dark Star' is VERY similar to 'Julia Phelps' but differs mainly in size. 'Dark Star' tends to stay a little smaller. Shrubby Ceanothus provide seeds eaten by bushtits, mockingbirds, quail and finches, as well as cover for birds.
Ceanothus ‘Frosty Blue’
A Rancho Santa Ana introduction from the mid 1970's. This upright evergreen shrub reaches 8 to 12 feet tall and 10 to 15 feet wide with glossy green, textured foliage. Flowers in late spring with 2-4 inch panicles of beautiful blue flowers with a frosted appearance due to the white bracts on the buds. Useful as a specimen or screen due to its rapid growth. Amenable to pruning and can be trained into a small tree or espaliered subject. This reliable cultivar tolerates heavy soils better than most upright Ceanothus. Does best in full sun and will be drought tolerant once established. California lilac are valuable additions to the habitat garden.
Ceanothus ‘Joan Mirov’
A naturally occurring hybrid from the Sonoma Coast selected by Roger Raiche and introduced by the U.C. Berkeley Botanic Garden. Low spreading habit with a dense form grows 4 ft. tall spreading widely 6-10 ft. or more. The small dark green shiny leaves are topped with an abundance of dark pink buds opening to cobalt blue flower clusters in the spring. An excellent bank cover where a dense ground covering shrub is needed on a sunny dry site. When planted inland a little afternoon shade and some summer irrigation is best. Ceanothus are valuable habitat plants where they offer food and cover and excellent forage for pollinators.
Ceanothus ‘Joyce Coulter’
A very useful medium sized mounding evergreen groundcover discovered in 1956 by John Coulter. Grows 2 - 5 ft. tall and spreads 12 ft. or more wide. Medium-blue flowers cover this shrub in spring. Tolerates garden conditions better than most Ceanothus. Responds well to shearing and can easily be kept to a more compact size. Plant in full sun where it is drought tolerant but best with some summer water in hot interior sites. Shrubby ceanothus provide seeds eaten by bushtits, mockingbirds, quail and finches, as well as cover for birds.
Ceanothus ‘Julia Phelps’
This much admired hybrid Ceanothus features a compact and bushy form, about 6 to 8 ft. tall and 8 to 10 ft. wide. Spectacular in spring when glowing dark indigo flowers cover the plant, accented by reddish buds. Small and crinkled dark green leaves provide an excellent backdrop for the richly colored flowers. Plant in full sun. Needs good drainage and summer drought once established. Does not do well in hot, interior climates. Very hard to distinguish from 'Dark Star', 'Julia Phelps' is somewhat larger. Shrubby Ceanothus provide seeds eaten by bushtits, mockingbirds, quail and finches, as well as cover for birds.
Ceanothus ‘Ray Hartman’
Beautiful large shrub rapidly grows 12 - 20 ft. tall and wide. Dark, shiny green foliage with large, medium blue spike-like flower clusters in the spring. Tolerates pruning and can be trained as a small tree or sheared to create a tall hedge. This selection is especially adaptable, tolerating heat, some summer water and drought. Plant in sun or very light shade. 'Ray Hartman' is a cross between the species C. arboreus and C. thyrsiflorus var. griseus. Ceanothus provide habitat and forage for a wide variety of birds, bees and butterflies.
Ceanothus arboreus ‘Cliff Schmidt’
Selected from Santa Cruz Island by Native Son's Nursery, this handsome cultivar has a strong upright habit, growing into a tall and spreading shrub as much as 15-20 ft. tall and wide. Large dark green glossy leaves have white felted undersides. Medium blue flower spikes blossom in late winter to early spring and often again in fall. Excellent for coastal gardens in full sun, give some afternoon shade and a little summer water in warmer inland sites. This large shrub can be pruned into a lovely small tree. Ceanothus are excellent additions to habitat gardens where they provide food, cover and nesting sites for birds and beneficial insects.
