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[1] fruits sold as "blueberries" and are native to North America (commercially cultivated highbush blueberries were not introduced into Europe until the 1930s).
