The Manzanitas are a subgenus 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 in Canada, Washington to California and New Mexico in the United States, and throughout much of northern and central Mexico. They are characterised by smooth, orange or red bark and stiff, twisting branches. There are about 60 species of manzanita, ranging from ground-hugging coastal and mountain species to small trees up to 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, though not particularly tasty.

Native 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 and drunk, making a refreshing cider. When the bark curls off, it can be used as a tea for nausea and upset stomach.

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, more usually known as madroño, or madrone.

Uses

Manzanitas (tree and larger shrub varieties) are sometimes used for ornamental plants, because of their high drought-tolerance and unusual bark and leaf colors. However, because most species grow slowly and in dense clusters, often a landscaper will simply remove all but a few attractive samples, which are then pruned of dead wood.

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 high number of branchings further decrease the sizes available. Some furniture and art utilizes 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 of the plant. It bleaches under sunlight to light grey or white tones and smooth surfaces, often times looking like animal bones. Because of this and the stunted slow growth of many species, it is often found in unusual shapes, and collected. This has resulted in the nickname mountain driftwood.

A more unusual market for manzanita wood is its use as perches for parrots and other large birds, kept as pets. The branches of the larger species are extremely long lasting in this regard.

Some aquarium keepers use sandblasted samples of the wood as driftwood in planted aquaria. They choose this hard wood for both its attractive forked growth patterns and for its chemical neutrality. If properly cleaned and cured, it holds up well over extended periods of submersion. Additionally, the wood is resistant to the leeching of tannins into the water column, a problem often associated with other types of driftwood used in aquaria. When used in this manner, Manzanita often must be either weighted down for a few weeks or soaked in advance to counteract the wood's natural buoyancy.

Manzanita wood, when dry, is a very good fuel for wood burning in a campfire, barbecue, fireplace, and 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.

Threats

Some manzanita species are among the rarest plants in the world. Arctostaphylos hookeri subsp. ravenii (also known as Presidio manzanita) is the most endangered and restricted plant on the mainland of the United States. In 1987 only one individual remained, at a secret location in the Presidio district of San Francisco, California. This plant has since been successfully cloned.
