The Arctostaphylos uva-ursi distribution is circumpolar, widespread in northern latitudes, confined to high altitudes further south:
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.
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.
There are four subspecies:
Bearberry has historically been used for medicinal purposes. It contains the glycoside arbutin, which has antimicrobial properties and acts as a mild diuretic. It has been used for urinary tract complaints, including cystitis and urolithiasis. An infusion may be made by soaking the leaves in ethanol and then diluting with water.
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.
