Cranberry

Cranberry, common name for several species of low vines of a genus of the heath family, and for their small, sour, seedy fruit. The plants, which belong to the same genus as the blueberry, have drooping, pink flowers and small, thick, evergreen leaves. The small, or European, cranberry grows wild in marshlands of temperate and colder regions of Europe and North America. The large, or American, cranberry is cultivated in the northeastern United States in sand-covered bogs that can be flooded or drained at will. Flooding protects the vines from frosts and freezing weather and destroys insect pests. Most of the cranberry crop produced in the United States each year is canned as sauce or jelly or bottled as juice. The cowberry, or mountain cranberry, is common in both Europe and North America. It is gathered and sold in considerable quantity but is rarely cultivated. The highbush cranberry, with its clusters of white flowers followed by red berries, is a shrub of the honeysuckle family. Its fruit is sometimes used as a substitute for cranberries.

Scientific classification: Cranberries belong to the genus Vaccinium of the family Ericaceae. The small, or European, cranberry is classifed as Vaccinium oxycoccos; the large, or American, cranberry as Vaccinium macrocarpon; and the cowberry, or mountain cranberry, as Vaccinium vitis-idaea. The highbush cranberry belongs to the family Caprifoliaceae and is classified as Viburnum opulus.
