Ceanothus x delileanus 'Topaz' ceanothus
More information »

Ceanothus x delileanus 'Topaz'

(ceanothus)

This non-native ceanothus is one of the French hybrids, similar to Ceanothus 'Gloire de Versailles'. They are the result of crosses between a Mexican species (C. coeruleus) and C. americanus from the eastern U.S.. In Europe they are espaliered for cold protection and tend to be fully deciduous. Here they can be grown as free-standing summer blooming pyramidal shrubs growing to 6 ft. tall and wide. The flower color is richer than 'Gloire de Versailles', a frosted blue or light indigo. Provide sun to light shade and moderate to infrequent irrigation. A hard pruning in late fall will encourage stronger flowering and keep a more compact form.

Ceanothus x pallidus 'Marie Simon'

(ceanothus)

A valuable but underutilized, semi-deciduous shrub with long blooming big, billowy pink flower clusters late spring to mid-summer. Grows 3 to 5 ft. tall and wide with handsome red stems. This French hybrid from the early 19th century is well used in mixed flower borders or with roses and other shrubs. Responds well to a hard cutting back while dormant which will help keep this shrub more compact. Provide moderate to occasional irrigation.

Cephalanthus occidentalis

(button willow)

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

(western redbud)

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)

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 ledifolius

(curl-leaf mountain mahogany)

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'

(dwarf Port Orford cedar)

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.

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.
