Overview
Comprehensive Description
Description
Pure stands of bearberry can be extremely dense, with heights rarely taller than 6 inches. Erect branching twigs emerge from long flexible prostrate stems, which are produced by single roots. The
trailing stems will layer, sending out small roots periodically. The finely textured velvety branches are initially white to pale green, becoming smooth and red-brown with maturity. The small solitary three scaled buds are dark brown.
The simple leaves of this broadleaf evergreen are alternately arranged on branches. Each leaf is held by a twisted leaf stalk, vertically. The leathery dark green leaves are an inch long and have rounded tips tapering back to the base. In fall, the leaves begin changing from a dark green to a reddish-green to purple.
Terminal clusters of small urn-shaped flowers bloom from May to June. The perfect flowers are white to pink, and bear round, fleshy or mealy, bright red to pink fruits called drupes. This smooth, glossy skinned fruit will range from 1/4 to 1/2 inch in diameter. The fruit will persist on the plant into early winter. Each drupe contains 1 to 5 hard seeds, which need to be scarified and stratified prior to germination to reduce the seed coat and break embryo dormancy. There is an average of 40,900 cleaned seeds per pound.

Distribution and adaptation
Bearberry’s native range is from Labrador to Alaska, south to Virginia, Illinois, Nebraska, and in the mountains from New Mexico north through California to Alaska. This long-lived, low growing shrub is very cold tolerant. This plant prefers coarse well to excessively drained soils of forests, sand dunes, bald or barren areas. It does not tolerate moist or off-drained sites. Although bearberry is often found growing in the open on sand dunes, it grows well under partial shade of forest canopies.
For a current distribution map, please consult the Plant Profile page for this species on the PLANTS Website.

Ecology
Dispersal
Establishment
Bearberry can be propagated from seeds, softwood cuttings or pre-rooted stem cuttings. It is difficult to root this plant from bare cuttings in the greenhouse. Scarified seed sown in early summer will improve germination the following spring, but this technique is not as reliable as cuttings. Softwood cuttings should be harvested in late summer, and rooted stem cuttings are most successful when harvested during the dormant season. Successfully grown seedlings or cuttings should be handled carefully in containers; bare root plantings are rarely effective.

There are no known varieties of bearberry available; local or regional selections are available from commercial nurseries.
Trusted
Management
This shrub species requires very little maintenance once it has been established. Annual spring applications of 10-10-10 will increase the growth rate of bearberry, but will also increase weed growth. Weed growth must be controlled to sustain healthy stands of bearberry.

Uses
Bearberry serves a dual role on sandy soils, as both a beautification plant as well as a critical area stabilizer. The thick, prostrate, vegetative mat and evergreen character are what make bearberry a very popular ground cover. It is often planted around home sites, sand dunes, sandy banks, and commercial sites. The fruit it produces is eaten by a few species of songbirds and game animals. Deer will sometimes browse the foliage lightly.

Distribution
The Arctostaphylos uva-ursi distribution is circumpolar, widespread in northern latitudes, confined to high altitudes further south:
- in Europe, from Iceland and North Cape, Norway south to southern Spain (Sierra Nevada), central Italy (Apennines) and northern Greece (Pindus mountains);
- in Asia from arctic Siberia south to Turkey, the Caucasus and the Himalaya;
- in North America from arctic Alaska, Canada and Greenland south to California, north coast, central High Sierra Nevada (above Convict Lake, Mono County, California), Central Coast, California, San Francisco Bay Area, to New Mexico in the Rocky Mountains; and the Appalachian Mountains in the northeast United States.
In some areas the plant is endangered or has been extirpated from its native range. In other areas it is abundant. They are a common plant in Jack pine areas.
Description
Arctostaphylos uva-ursi is a small procumbent woody groundcover shrub 5-30 cm high. The leaves are evergreen, remaining green for 1–3 years before falling. The fruit is a red berry.
The leaves are shiny, small, and feel thick and stiff. They are alternately arranged on the stems. Undersides of leaves are lighter green than on the tops. New stems can be red if the plant is in full sun, but are green in shadier areas. Older growth stems are brown. In spring, they have white or pink flowers.
Subspecies
There are four subspecies:
- Arctostaphylos uva-ursi subsp. uva-ursi. Common Bearberry; circumpolar arctic and subarctic, and in mountains further south.
- Arctostaphylos uva-ursi subsp. adenotricha. Central high Sierra Nevada.
- Arctostaphylos uva-ursi subsp. coactilis. North coastal California, central coast California, San Francisco Bay Area.
- Arctostaphylos uva-ursi subsp. cratericola (J. D. Smith) P. V. Wells. Guatemala Bearberry, endemic to Guatemala at very high altitudes (3000-4000 m).
Uses
Medicinal
Bearberry has historically been used for medicinal purposes. It contains the glycoside arbutin, which has antimicrobial properties and acts as a mild diuretic.[citation needed] It has been used for urinary tract complaints, including cystitis and urolithiasis.[citation needed] An infusion may be made by soaking the leaves in ethanol and then diluting with water.
Cultivation
There are several cultivars that are propagated for use as ornamental plants. It is an attractive evergreen plant in gardens, and it is also useful for controlling erosion.
