Arctostaphylos uva-ursi (L.) Spreng.

Bearberry, kinnikinnick, common bearberry

Bearberry is a hardy mat-forming evergreen shrub, widely distributed across subarctic North America. “Uva-ursi” means “bear’s grape”: bearberry is favored by bears and many birds. It is native to North America, Europe, the Iberian Peninsula, Siberia, and the Himalayas.

Plants: A low-growing evergreen ”subshrub” 1¾–12″ (5–30 cm) in height. Branches are white to pale green, almost velvety, later becoming smooth and red-brown. These plants’ dark green shiny leaves and red, hard berries about ¼″ (6.3 mm) in diameter resemble cranberries, but they are not related to them. Bearberry leaves look a little like a shoehorn, wider at one end than at the other, while cranberry leaves are about the same size at both ends and mountain cranberry has sharper tips.

Leaves: Shiny, thick, dark green on top and lighter below, 1½ ⨉ ⅜″ (4 ⨉ 1 cm), with rounded tips.

Flowers: Flowers are white, urn-shaped like blueberry flowers, and tinged with pink. They appear from May to June.

Fruits: Smooth, round, similar to cranberries, ⅛–½″ (6–13 mm) around.

Habitats: Acidic, dry to medium, well-drained, sandy or gritty soils in full sun. Circumpolar.

Edibility: Drupes are bitter, mealy, and flavorless when raw, but edible when boiled, dried, and sweetened. Each drupe contains 1-5 nutlets. Meriwether Lewis described these fruits in 1806 to be “tasteless and insipid.”
