California Coffeeberry

California CoffeeberryCalifornia coffeeberry is a species of flowering plant in the buckthorn family native to western North America and which is present in the San Bernardino Mountains. It has been scientifically classified as frangula californica and (previously as rhamnus californica). It is sometimes referred to as California buckthorn.
The plant occurs in oak woodland and chaparral habitats at various places in California, the Southwestern United States, and Baja California. It is an introduced species in Hawaii.
Frangula californica is a large, evergreen shrub with an open structure and shiny, dark leaves growing most often three to 12 feet tall, but occasionally to 15 feet or more in the shade. In the sun, it is more compact with lighter grey-green leaves. In favorable conditions the plant can develop into a small tree over 12 feet tall. Individual plants can live an estimated 100 to 200 years. The branches may have a reddish tinge and the new twigs are often red in color. The alternately arranged evergreen leaves are dark green above and paler on the undersides. The leaves have thin blades in moist habitat, and smaller, thicker blades in dry areas.
The 1/8 inch greenish flowers occur in clusters in the leaf axils, have 5 sepals, and 5 shorter petals. This plant blooms in May and June. The fruit is a juicy drupe which may be green, red, or black. It is just under a centimeter long and contains two seeds that resemble coffee beans.
This shrub is a member of many plant communities and grows in many types of habitat, favoring open woodland, brush canyonsides, chaparral, coastal sage scrub, California oak woodlands, foggy coastal oak woodlands, Coast redwood forests, California mixed evergreen forests, and mountain coniferous forests. It can be found alongside chaparral whitethorn (Ceanothus leucodermis), toyon (Heteromeles arbutifolia), skunkbush (Rhus trilobata), redberry (Rhamnus crocea), and western poison oak (Toxicodendron diversilobum). In brushy mountain habitat it grows among many species of manzanita.
The plant reproduces sexually by seed and vegetatively by sprouting. After wildfire or cutting, the plant generally resprouts from its root crown. Reproduction via seed is most common in mature stands of the plant. It produces seeds by two to three years of age. Seeds are mature in the fall. Seed dispersal is often performed by birds, which are attracted to the fruit; some plants are so stripped of fruit by birds that hardly any seeds fall below the parent plant.
This long-lived plant is persistent and becomes a dominant species in many habitat types, such as coastal woodlands. In the absence of wildfire, the shrub can grow large, with a wide spread that can shade out other flora. When fire occurs, the plant can be very damaged but it readily resprouts from the surviving root crown, which is covered in buds for the purpose. It reaches its pre-burn size relatively quickly.
Parts of the plant, including the foliage and fruit, are food for wild animals such as mule deer, black bears, and many resident and migrating birds, as well as livestock.
This plant is cultivated as an ornamental plant by plant nurseries, for planting in native plant, water conserving, and wildlife gardens; in large pots and containers; and in natural landscaping and habitat restoration projects. It is also used for erosion control, and is usually deer resistant. As a pollinator plant it is of special value to native butterflies and bees.
The seeds inside the berries make an excellent, caffeine-free coffee substitute, superior to chicory and with overtones of mocha. Although the plant itself looks much like a coffee plant, its berries, which are succulent, do not, but they can be made into jams and jellies.
Native Americans of the west coast of North America had several uses for the plant as food, and used parts of it as a traditional medicinal plant. Several tribes of the indigenous peoples of California ate the fruit fresh or dried.[28]
The Ohlone people used the leaves to treat poison oak dermatitis. The Kumeyaay people had similar uses for its bark. The Kawaiisu used the fruit to treat wounds such as burns. The bark was widely used as a laxative by the indigenous peoples. Names for the plant in the Konkow language of the Concow tribe include pä and pö.
