Huckleberry is a name used in North America for several plants in two closely related genera in the family Ericaceae: Gaylussacia and Vaccinium. The huckleberry is the state fruit of Idaho.
Some Vaccinium species, such as the red huckleberry, are always called huckleberries. Other species may be called blueberries or huckleberries in different locations.
There is much confusion in naming of berries in American English. The 'garden huckleberry' (Solanum melanocerasum) is not a true huckleberry but a member of the nightshade family.
