Arctostaphylos pumila aka Sandmat Manzanita

Arctostaphylos pumila is an evergreen shrub in the heath family, Ericaceae. Its common names are sandmat manzanita and dune manzanita. It comes from the central coast of California, around Monterey Bay. Its native range is small and confined to that area. Kew lists its native climate as subtropical. This is a low, spreading plant rather than a tree. Its species name, pumila, refers to its dwarf size.

The branches spread to form a mat or low mound. Plants reach about 3 feet [0.9 metres] in height. Some can grow to nearly 5 feet [1.5 metres]. Oregon State describes it as both a shrub and ground cover. Its low form gives it a ground-cover role in gardens. The bark has a reddish tone. Fine gray hairs cover the twigs, adding a softer look beside the bark.

The leaves are small, simple, and set alternately along the stems. They spread outward rather than lying against the shoots. Each blade narrows toward a wedge-shaped base. The wider end often has a blunt tip. Leaves measure about 0.4–0.8 inches long and 0.2–0.6 inches wide. Their edges lack teeth and may cup or roll slightly. The two leaf surfaces differ in both color and texture. The upper side curves outward and is dark green. It may shine, with scattered hairs that fade as leaves age. Fine gray hairs cover the lower side.

Small, loose flower clusters are white or tinged with pink. These pale blooms contrast with the dark upper leaf surfaces. The fruit is brownish and roughly round. Each fruit measures about 0.2 inches across. Its surface loses its hairs as it develops. The supplied species account does not give a flowering season. It also gives no evidence for eating the fruit or other parts.

Oregon State recommends sun for plants grown near the coast. Inland, it suggests a site with light shade. The plant needs little or no water during summer. That makes low-water planting a supported garden use. Oregon State places its cold hardiness at USDA Zone 9. The supplied accounts do not identify specific pests or diseases. They also provide no species-level toxicity assessment for people or pets.
