Manzanita is a common name for many species of the genus Arctostaphylos. They are evergreen shrubs or small trees present in the chaparral biome of western North America, where they occur from southern British Columbia and Washington to California, Arizona and New Mexico in the United States, and throughout Mexico. They are characterized by smooth, orange or red bark and stiff, twisting branches. There are 105 species and subspecies of manzanita, 95 of which are found in the Mediterranean climate and colder mountainous regions of California, ranging from ground-hugging coastal and mountain species to small trees up to 20 feet (6m) tall. Manzanitas bloom in the winter to early spring and carry berries in spring and summer. The berries and flowers of most species are edible.Mansanita snails are found on the branches.
The word manzanita is the Spanish diminutive of manzana (apple). A literal translation would be little apple. The name manzanita is also sometimes used to refer to species in the related genus Arbutus, which is known by that name in the Canadian area of the tree's range, but is more usually known as madroño, or madrone in the United States.
Traditional uses of the plant include collecting the berries, drying them, and grinding them up into a coarse meal. Fresh berries and branch tips were also soaked in water to make a cider. Native Americans used Manzanita leaves as toothbrushes.[unreliable source?] It[vague] was also used as substitute for sugar.
Manzanitas are extremely useful as ornamental plants in gardens in the western United States and similar climate zones. They are evergreen, highly drought-tolerant, have picturesque bark and attractive flowers and berries, and come in many sizes and growth patterns.
Arctostaphylos columbiana, for example, is hardy enough to be used for highway landscaping in western Oregon and Washington. Arctostaphylos 'Emerald Carpet', A. uva-ursi (the Bearberry), and other low-growing manzanitas are extremely valuable evergreen groundcovers for dry slopes. Larger varieties, such as Arctostaphylos. 'Dr. Hurd,' can be grown as individual specimens, and pruned to emphasize the striking pattern and colors of the branches. They prefer light, well-drained soil, although the low-growing ground covers will tolerate heavier soils.
Manzanita branches are popular as decoration, due to their unique shape, color, and strength when dried. Florists sometimes use them as centerpieces at wedding receptions and other events, often adding hanging votive candles, beaded gems and small flowers to them.
The wood is notoriously hard to cure, mostly due to cracking against the grain, giving it few uses as timber. The slow growth rate and many branchings further decrease the sizes available. Some furniture and art employ whole round branches, which reduces cracking and preserves the deep red color.
The dead wood decays slowly and can last for many years, on and off the plant. Sunlight smooths and bleaches manzanita to light grey or white, rendering it superficially akin to animal bones. Because of this and the stunted growth of many species, manzanita is often collected in its more unusual shapes, giving it the nickname mountain driftwood.
Manzanita wood is also used as perches for parrots and other large pet birds. The branches of the larger species are extremely long-lasting for this purpose. Some aquarium keepers use sandblasted manzanita as driftwood in planted aquaria because of its attractive forked growth and its chemical neutrality.
If properly cleaned and cured, it holds up well over extended periods of submersion. The wood is also resistant to the leaching of tannins into the water column, a problem often found with other aquarium driftwoods. When used as driftwood, manzanita must often be either weighted down for several weeks or soaked first to counteract the wood's natural buoyancy.
Manzanita wood, when dry, is excellent for burning in a campfire, barbecue, fireplace, or stove. It is dense and burns at a high temperature for long periods. However, caution should be exercised, because the high temperatures can damage thin-walled barbecues, and even crack cast iron stoves or cause chimney fires.
Rarity and endemics
Some manzanita species are among the rarest plants in the world. The endemic Arctostaphylos hookeri ravenii (Presidio manzanita) is the most endangered and restricted plant in the mainland United States. In 1987 only one specimen remained, at a secret location in the Presidio of San Francisco National Historic Landmark District in San Francisco, California. This plant has since been successfully cloned. Arctostaphylos franciscana (Franciscan Manzanita), a species native to San Francisco, had not been seen growing wild since 1947 until it was spotted growing in the Presidio of San Francisco in October 2009. Caltrans transplanted this specimen on 23 January 2010 to make way for the Doyle Drive Replacement Project. Transplanting costs were funded in part by Federal Highways Administration, Caltrans, The Presidio of San Francisco, and private donors.
Genus evolution is relatively recent; however, in Hogan's tracing of the genus evolutionary history: "convergent evolution patterns appear to complicate cladistic constructions for certain portions of the genus cladogram. In any case, fossil ancestors of the Arctostaphylos genus have been suggested to have occurred in the Middle Miocene, with modern species beginning to take shape in the Late Tertiary."
