In the United States, the name huckleberry is often used for blueberry, which see. While the two fruits are similar in appearance and flavor, the huckleberry which is a drupe has a 10-celled ovary, each cell (drupelet) normally containing a seed large enough to be conspicuously noticeable when the whole fruit is eaten. Blueberries, in contrast, contain many seeds so small as not to be noticeable when the fruit which is a berry is consumed. Only blueberries are a cultivated crop, but quantities of huckleberries are harvested from native plants. The huckleberry plant is a shrub, to 6 feet, with small, entire oval leaves. Fruits are borne in small clusters. Individual fruits are generally one-third inch or less in diameter, mainly blue to black in color, sweet or slightly tart when ripe. Several species, mainly in Eastern United States, produce fruits valued locally.
