Ceanothus velutinus
Found primarily in the northern half of the state in the Coast Ranges, Sierras, Klamath and Modoc regions, in coniferous forests, chaparral, and various woodland environments up to 11,000 ft in elevation, the resinous floral scent and plumes of soft white flowers from spring to early summer make tobacco brush a choice evergreen shrub for dry, sunny to part-shade garden sites that drain well. Grows to 6-10 ft tall, and has large, sticky dark-green, aromatic, leathery foliage. A larval host for many native butterfly species such as the ceanothus silk moth, California tortoiseshell butterfly, and the hedgerow hairstreak butterfly. The flowers are also attractive to native bee and butterfly pollinators. Drought-tolerant once established.
Cephalanthus occidentalis
Button willow is a large deciduous shrub, at times becoming treelike, growing 6-12 ft. (infrequently as much as 20 ft.) tall and wide. It lines waterways in foothills and warm interior valleys. Smooth, glossy bright- green leaves clothe this shrub during the growing season, turning yellow in the autumn. Creamy white flowers are arranged in spherical heads with protruding styles which give the flowers a pincushion-like appearance. The summer blooming, fragrant flowers are extremely rich in nectar and attract bees, butterflies and other pollinators. The globe-like fruits persists into winter and attract birds. Plant in sun to light shade with regular summer water or continuously moist or wet soils. An excellent habitat plant offering food and cover for a wide array of insects and birds.
Cercis occidentalis
Beautiful in all its seasons, the native redbud is well worth growing. Highly ornamental multi-trunked shrub or small tree 6 - 20 ft. tall and wide. Masses of brilliant rose-purple blossoms in early spring followed by conspicuous long seed pods that start out lime green and age to purple-brown. The rounded heart-shaped leaves emerge apple green and develop to bluish-green. In colder areas, the leaves take a nice fall color of yellow or red. The smooth silvery-gray branches are picturesque in the winter landscape. Plant in full sun to light shade with good drainage. Drought tolerant. Important nectar and pollen source for bees. Attracts hummingbirds too.
Cercocarpus betuloides
Mountain mahogany is an adaptable, semi-evergreen native shrub (8 to 12 ft. high and wide) or small tree with charming birch-like leaves set against silver-grey bark. Small, honey-scented flowers appear in spring followed by seeds with intriguing silky, curled, feather-like tails. The open habit contrasts nicely with evergreen shrubs or rock walls where its pleasing silhouette can be seen. Flowers are attractive to bees. Mountain mahogany is one of those rare native shrubs which can easily be pruned for narrow garden beds. Grows on dry slopes in chaparral or at the edges of woodlands. Provide full sun to light shade. It is surprisingly adaptable to diferent water regimes, from moderate irrigation to no water once established. Somewhat deer resistant.
Cercocarpus betuloides var. blancheae
This rare and beautiful variety of our native mountain mahogany offers larger, birch-like leaves with fuzzy and whitish undersides. The highly useful from generally reaches 8 – 15 ft. tall, but only spreads to about 6 ft. wide, making it ideal for narrow locations where a screening, evergreen, fast-growing bush is needed. Small, disk-like, creamy flowers appear in the spring, followed in summer by seed pods with hairy, grey tails which curl upwards, giving the plant a silver halo. Over time, the trunks are covered in a smooth, grey bark. The Island mountain mahogany typically grows much more rapidly than our local variety and is tolerant of moist or dry soils once established and part shade to full sun. Heat isn’t an issue. A great candidate for a container, where it is very amenable to pruning.
Cercocarpus ledifolius
Large shrub or small, multitrunked, evergreen tree, 6 - 30 ft. tall, native to arid mountains of the western US. Often takes on a gnarled, picturesque form depending on the conditions it is growing in. Adapted to dry, rocky slopes where it weathers drought, extreme heat and cold, wind and snow. Slow growing, densely branching, with dark green, leathery leaves with curled under edges and silvery undersides. Trunks develop beautiful, red-brown bark with silvery new growth. The flowers are similar to our local mt. mahogany species, small, greenish- yellow, smelling of honey, and attractive to pollinators. The fruits are long, silvery, plumes that glow when back lit. Plant in full sun to light shade with good drainage where it will blend well with other dryland shrubs and perennials and requires little input. Fixes nitrogen. Interesting container or bonsai subject.
Chamaecyparis lawsoniana ‘Nidiformis’
A very unusual and hard to find form of the native Port Orford cedar. Nidiformis is Latin for “having the form of a nest”, an apt descriptor for this dwarf with dense growth and graceful, cascading branches. The delicate, finely dissected foliage is grey-green with hints of blue, providing an excellent contrast to large-leaved, dark-colored perennials. Very slow growing, usually forming a low mound a few ft. high and several ft. wide. Needs good drainage and moderate to infrequent irrigation. Enjoys full sun near the coast, but wants some afternoon shade in hot climates. Good in a container.
Chilopsis linearis
A graceful, summer-blooming, deciduous shrub, native to desert washes where it grows in gravelly soils and intense heat.

Terminal clusters of showy, trumpet-shaped flowers in summer come in shades of white, to pink and purple that attract hummingbirds and butterflies. Long, bean-like pods follow and hold on into winter. Enjoys hot climates with plenty of sun, decent drainage and occasional to moderate water. Avoid cool coastal conditions and heavy wet soils. Grows fast when happy with no pest or disease problems, demanding little. A great option for along sidewalks.
Chlorogalum angustifolium
You may be familiar with the common soap plant and its tall stalks of delicate white flowers. But this unusual, diminutive species of soap root is much smaller, only reaching 1 – 2 ft. high. Rarely offered in nurseries, this species has short, narrow leaves which are not wavy like the common soap plant. Grows in dry grassland and open woodlands in the northern Sierra foothills and coast range. Enjoys full sun to light shade and no additional irrigation once established. Tolerates clay. The seed for these plants came from Windsor and was generously given to us by Vicki Wilson.
Chlorogalum pomeridianum v. pomeridianum
Known for their large, fibrous bulbs historically used by indigenous peoples and early settlers for soap, food and to stupefy fish. Long, wavy-margined leaves form a rosette in winter followed in late spring by tall, airy flower stems bearing small white flowers that open in the late afternoon and evening. Great in naturalistic settings in full sun to light shade. Needs to go summer dry once established. Larval food source for the Western Brown Elfin butterfly.
Cirsium occidentale
A beautiful NATIVE and NON-WEEDY thistle. Forms a rosette of gray woolly and spiny leaves the first year.

This endemic, ANNUAL wildflower grows in openings of woodlands and chaparral near the coast, mostly in the central part of state. Grows 2-ft. tall or more in full sun with low water needs. Tolerant of heavy soils, the exuberant blossoms attract bees, butterflies and moths, including Sphinx moth species. Performs well in containers and is an excellent cut flower too. Deer resistant.
Clarkia williamsonii
The incredibly showy flowers of this native ANNUAL will take your breath away in late spring and early summer. The large, lavender-pink, papery flowers feature deep, burgundy-red brush strokes and cheery white centers. Plants form a loose mound about 1 ½ ft. around.
