"It is a small procumbent woody 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 in areas with high sun, but are otherwise green. Older growth stems are brown. In spring, they have white or pink flowers. They are a common plant on Jack pine sites.

"The distribution is circumpolar, widespread in northern latitudes, confined to high altitudes further south. 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.

"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).

"There are also several varieties that are propagated for use as ornamentals. It is an attractive evergreen plant and it is also useful for controlling erosion."
