The traditional English name for the plant more common in Europe, Vaccinium oxycoccos, fenberry, originated from plants with small red berries found growing in fen (marsh) lands of England.[13]

Cranberries are a group of evergreen dwarf shrubs or trailing vines in the subgenus Oxycoccus of the genus Vaccinium. In Britain, cranberry may refer to the native species Vaccinium oxycoccos,[1] while in North America, cranberry may refer to Vaccinium macrocarpon.[2] Vaccinium oxycoccos is cultivated in central and northern Europe, while Vaccinium macrocarpon is cultivated throughout the northern United States, Canada and Chile.[3] In some methods of classification, Oxycoccus is regarded as a genus in its own right.[4] They can be found in acidic bogs throughout the cooler regions of the Northern Hemisphere.
