Gaylussacia brachycera, commonly known as box huckleberry or box-leaved whortleberry, is a low North American shrub related to the blueberry and the other huckleberries. It is native to the east-central United States (Pennsylvania, Delaware, Maryland, Virginia, West Virginia, North Carolina, Kentucky, and Tennessee). Gaylussacia brachycera is easily distinguished from other members of its genus by its leaves: they resemble those of boxwood (hence its name) and lack the resin glands typical of huckleberries. Like its relatives, it bears white urn-shaped flowers in the early summer, which develop to blue, edible berries in late summer. Plant in well-drained soil in a suitable position. Water during establishment.
