Chaparral whitethorn (Ceanothus leucodermis) is an evergreen shrub in the Buckthorn family. It’s native to California and Baja California, where it grows in coastal and inland mountain habitat. 

This large shrub has thorns that grow along the stem. Its blue-green leaves are small and oval and contrast nicely with the gray-white, waxy stem. Chaparral whitehorn blooms in spring, with long clusters of tiny flowers in shades of blue, lavender, or white. The small fruit is a sticky, yellow-green capsule small mammals, birds, and insects eat. Mule deer and bighorn sheep browse the new growth and shoots.

This ceanothus is easy to grow if it’s properly sited. It prefers the mountains or interior valleys to the coast. Plant on a slope among other shrubs to protect the roots from direct sun. 

Ceanothus maritimus is a rare, narrow endemic species of shrub in the Buckthorn family (Rhamnaceae) known by the common name Maritime Ceanothus. It is endemic to San Luis Obispo County, California, where it is known from only a few occurrences in the vicinity of Hearst Ranch. It shares the same range as the similarly rare Ceanothus hearstiorum, growing on the coastal bluffs.

This species looks unlike other Ceanothus and is said to resemble the non-native Cotoneaster. This is a spreading or ascending shrub under a meter in height with reddish gray bark aging to gray. The firm evergreen leaves are oppositely arranged, each oval or oblong in shape with a pointed, flat, or notched tip. Its short leaves are shiny green on top and woolly underneath, with their edges curled under and sometimes toothed.

The flower cluster is a small cluster of deep blue to off-white flowers. The fruit is a capsule, generally rounded with tiny horns on top. This is an attractive, adaptable, long-lived plant that is great for central coastal gardens.

Tolerates almost any soil type. Prefers sun in coastal sites, and part shade in inland sites. Selected for the garden.

Blueblossom ceanothus (Ceanothus thyrsiflorus) is a large shrub or small tree in the Buckthorn family (Rhamnaceae). Evergreen, glossy leaves range from bright green to dark green. Small flower clusters range in color from light blue, dark blue, or blue-violet; occasionally a specimen with pale blue-white flowers can be found. Varying dramatically in form and size over its natural range, some plants grow fairly upright to 30 feet and others grow in a mounding form to only 2-3 feet tall. Flowers appear in late winter or early spring, and are an important early source of food for pollinators. Bees are especially attracted to the flowers. Three-lobed seed capsules are eaten by birds and small mammals. 

Blueblossom grows primarily along the coast and coastal mountains, in many different habitats, in full sun or part shade. In the hotter, inland part of its range, it can be found growing in the shade of northern slopes, under mature woodland canopies, or closer to an irrigated or a naturally moist area. In the cooler, coastal areas, it prefers more sun and dry locations.

In the garden, if you continue to provide summer irrigation after it is established, ceanothus species will usually be short-lived. Choose a ceanothus which is native to your location, then stop irrigating after year two or three. Blueblossom can be used alone as a backdrop to shorter shrubs and perennials, or as an evergreen hedge. Prune it to one trunk for a treeform, or keep it natural for a large shrub. When in bloom, blueblossom is almost entirely covered in flowers, creating a dreamy blue haze in the landscape. There are many cultivars available at nurseries all over the state.

Foundation 1956 .Tolerates almost any soil type. Prefers sun in coastal sites, and sun or part shade in inland sites. Selection developed by Maunsell Van Rensselaer in 1954. Species previously known as C. griseus var. horizontalis.

Creeping Blueblossom (Ceanothus thyrsiflorus var. thyrsoflorus) is a the low growing form and variety of the native shrub and tree Ceanothus thyrsiflorus. It native range is coastal central and northern California, extending from northern Santa Barbara County to near the Oregon border, growing 1- 5 miles from the shore. The other variety of this species, Ceanothus thyrsiflorus var. griseus (Carmel Ceanothus) is much more variable in form and is native to habitats closer to the coast.
Creeping Blueblossom was previously classified as Ceanothus thyrsiflorus var. repens.

Creeping Blueblossom has profuse attractive sky blue flowers and makes an excellent ground cover plant. It prefers full sun to part shade in cooler coastal environments, and part shade to full shade in hotter and drier inland environments. It tolerates occasional light summer water, but is quite drought tolerant. It grows well in many different soil types, from clay to sand, and can tolerate poorly draining and fast draining conditions.

Cultivars in the nursery trade include:
Ceanothus thyrsiflorus var. thyrsiflorus 'Taylor's Blue' (Taylors Blue Ceanothus). This is a shrub ground cover growing 2-3 feet tall by 10-15 feet wide. It was introduced in the 1950s as Ceanothus thyrsiflorus 'Louis Edmunds' by the Saratoga Horticultural Foundation, from a plant in nurseryman Ken Taylor's natives garden in Aromas, originally from the garden of nurseryman Louis L. Edmunds. It was previously named and is sometimes still sold as C. t. var. repens 'Taylor's Blue'.
Ceanothus thyrsiflorus var. thyrsiflorus 'Louis Edmunds' (Louis Edmunds Blue Blossom). This is a prostrate ground cover growing 6 inches tall by 6 to 8 feet wide, and is the lowest cultivated form of C. t. var. thyrsiflorus. It introduced by Rancho Santa Ana Botanic Garden (California Botanic Garden) in 1958 as Ceanothus griseus 'Louis Edmunds' from a plant given them by Louis L. Edmunds, who operated the Louis Edmunds Native Plant Nursery in Danville.
This is not the same plant as the cultivar Ceanothus thyrsiflorus var. griseus 'Louis Edmunds' (Louis Edmunds Carmel Ceanothus) nor the formerly named Ceanothus thyrsiflorus 'Louis Edmunds' (currently C. t. var. thyrsiflorus 'Taylors Blue').

Ceanothus tomentosus is a species of shrub in the Buckthorn family (Rhamnaceae) known by the common name Woollyleaf Ceanothus. It is most commonly found in the foothills and canyons of San Diego, Orange and Riverside Counties, north up into the foothills of the Transverse Mountains, and south down into Baja California. The plants formerly called Ceanothus tomentosus var. tomentosus from the Sierra Nevada are actually more closely related to Ceanothus thyrsiflorus (see Burge et. al. Nov. 2011). Ceanothus tomentosus grows in chaparral, coastal sage scrub, coastal strand and foothill woodland plant communities in its range.

It is shrub approaching four meters in maximum height. The evergreen leaves are alternately arranged and have dense, matted hairs on the undersides. The leaves have tiny, hairy teeth. The flower cluster is several centimeters long of deep blue or white flowers. The fruit is a lobed capsule a few millimeters long. It is not hairy and it is sticky when new.

Ceanothus tomentosus is a quintessential chaparral plant in San Diego county. It puts on a great floral display for 1-2 months in winter or occasionally in the spring if rains come late. The flowers are beautiful and abundant particularly in wetter years, and can turn the foothills and canyons blue. So for 1-2 months this plant is especially spectacular. The shiny leaves reflect the sun and look beautiful when backlit. In southern California, it prefers full sun and slopes that retain just a bit more moisture than average - i.e. north facing slopes, slope bottoms, east or west facing slopes with heavier soils and plenty of rocks, or cool coastal conditions. Fast growing to 6-12 feet if happy.

Ceanothus tomentosus doesn't tolerate much if any direct summer water after it's established, and if planted in soils that don't retain enough moisture, it will dry out and die. So site selection is very important here. Best to give it regular water for the first year, and none or almost none thereafter, though it'll do fine if planted adjacent to an irrigated area. If you do give it supplemental water, it should be light and preferably indirect. It will typically drop about half its leaves in the summer and make its own mulch.

Ceanothus velutinus is a species of shrub in the buckthorn family, Rhamnaceae, known by the common names Red Root, Snowbrush Ceanothus and Tobacco Brush. It is native to western North America from British Columbia to California to Colorado, where it grows in several habitat types including coniferous forest, chaparral, and various types of woodland. In California it is found primarily in the northern half of the state in the Coast Ranges, Sierras, Klamath and Modoc regions. It can grow up to 4 meters tall but generally remains under three, and forms colonies of individuals which tangle together to form nearly impenetrable thickets. The aromatic evergreen leaves are alternately arranged, each up to 8 centimeters long. The leaves are oval in shape with minute hairy teeth along the edges, and shiny green and hairless on the top surface. The plentiful flower clusters are long clusters of white flowers. The fruit is a three-lobed capsule a few millimeters long which snaps open explosively to expel the three seeds onto the soil, where they may remain in a buried seed bank for well over 200 years before sprouting. The seed is coated in a very hard outer layer that must be scarified, generally by wildfire, before it can germinate. Like most other Ceanothus, this species fixes nitrogen via actinomycetes on its roots.

Ceanothus verrucosus is a rare species of shrub in the Buckthorn family (Rhamnaceae) known by the common names wart-stem ceanothus, barranca brush, and white coast ceanothus. It is endemic to Baja California and San Diego County, where it grows in coastal chaparral and scrub. Much of the coastal land that hosts this plant in the San Diego area has been claimed for development, but many populations still remain scattered around the region, such as one protected at Torrey Pines. This is an erect shrub approaching 3 meters in maximum height. The evergreen leaves, each up to about 1.5 centimeters long, are alternately arranged on bumpy stems. The flowers are held in a cluster up to around a foot. The flower is white except for its characteristic dark center. The fruit is a capsule about half a centimeter long.

Ceanothus verrucosus is one of the easier Ceanothus species to grow in southern California. It seems to tolerate summer water slightly better, and tolerates tough drought conditions much better than most other southern California Ceanothus species. But it does best with monthly summer water it's first year, and then left alone after that. It produces a spectacular display of white flowers in late winter, often early March. It tends to grow in an attractive fanned-out form, and its leaves stay green and healthy looking even through a long dry summer with no water.

Celtis laevigata, the Sugarberry, is a medium-sized tree native to North America. It is also sometimes referred to as Southern Hackberry, or in the southern U.S. Sugar Hackberry or just Hackberry. Sugarberry is easily confused with Common Hackberry, (Celtis occidentalis) where the range overlaps. Sugarberry has narrower leaves which are smoother above. The species can also be distinguished by habitat: where the ranges overlap, Common Hackberry occurs primarily in upland areas, whereas Sugarberry occurs mainly in bottomland areas.

Celtis reticulata, or Netleaf Hackberry, is a medium-sized tree native to North America. The tree was first described in the mid nineteenth century by observations in the lower elevations of the Rocky Mountains as well as observations in lower montane areas of Oregon. C. reticulata was one of the species analyzed in a pollen core samplng study in northern Arizona, in which the early to late Holocene flora association was reconstructed; this study in the Waterman Mountains demonstrated that C. reticulata was found to be present after the Wisconsinan glaciation, but is not a current taxon of this Pinyon-juniper woodland area. The leaves are eaten by a number of insects, particularly certain moth caterpillars.

Centromadia fitchii, Fitch's spikeweed or Fitch's tarweed, is a species of North American plants in the tarweed tribe within the sunflower family. It is native to California and southwestern Oregon. Centromadia fitchii is an herb up to 50 cm (20 inches) tall. It produces arrays of numerous yellow flower heads with both ray florets and disc florets.
