Blueberries are perennial flowering plants with indigo-colored berries in the section Cyanococcus within the genus Vaccinium (a genus that also includes cranberries and bilberries). Species in the section Cyanococcus are the most common fruits sold as “blueberries” and are native to North America (commercially cultivated highbush blueberries were not introduced into Europe until the 1930s).
