Cranberries are tart, red edible berries from evergreen dwarf shrubs in the genus Vaccinium, subgenus Oxycoccus. In North America, the term usually refers to Vaccinium macrocarpon, the main commercial species.

What it is

Cranberries are low-growing evergreen shrubs or trailing vines with slender stems and small leaves. The fruit starts light green and turns red when ripe. The main commercial species is Vaccinium macrocarpon, while Vaccinium oxycoccos is common in Europe.

Where it grows

Cranberries are native to acidic bogs and wetlands in cooler regions of the Northern Hemisphere. Wild American cranberry grows across northeastern North America. Commercial cultivation is concentrated in parts of the United States, Canada, and Chile.

How it's used

Cranberries are harvested in flooded bogs and used fresh or processed into juice, sauce, jam, and dried products. They are especially associated with North American and Canadian holiday cooking, such as cranberry sauce with turkey.

In short

  • Cranberries are native to acidic bogs in cooler Northern Hemisphere regions.
  • The main species in North America is Vaccinium macrocarpon.
  • They are widely used in juice, sauce, and preserves.
