Cranberries are a group of evergreen dwarf shrubs or trailing vines in the genus Vaccinium subgenus Oxycoccus, or in some treatments, in the distinct genus Oxycoccus. They are found in acidic bogs throughout the cooler parts of the Northern Hemisphere.
Cranberries are low, creeping shrubs or vines up to 2 m long and 5 to 20 cm in height, with slender, wiry stems, not thickly woody, and small evergreen leaves. The flowers are dark pink, with very distinct reflexed petals, leaving the style and stamens fully exposed and pointing forward. They are pollinated by domestic honey bees. The fruit is a berry that is larger than the leaves of the plant; it is initially white, but turns a deep red when fully ripe. It is edible, with an acidic taste that can overwhelm its sweetness.
Cranberries are a major commercial crop in certain US states and Canadian provinces. Most cranberries are processed into products such as juice, sauce, and sweetened dried cranberries, with the remainder sold fresh to consumers. Cranberry sauce is regarded an indispensable part of traditional American and Canadian Thanksgiving menus and European winter festivals.
