While some Vaccinium species, such as the Red Huckleberry, are always called huckleberries, other species may be called blueberries or huckleberries depending upon local custom. Similar Vaccinium species in Europe are called bilberries.
Note that there is much confusion in naming of berries in American English. The 'garden huckleberry' (Solanum melanocerasum) is not considered to be a true huckleberry but a member of the nightshade family.
The fruit of the various species of plant called huckleberry is generally edible. The berries are small and round, usually less than 5 mm in diameter, and contain 10 relatively large seeds. Berries range in color according to species from bright red, through dark purple, and into the blues. In taste the berries range from tart to sweet, with a flavor similar to that of a blueberry, especially in blue/purple colored varieties. Huckleberries are a favorite of many animals such as bears and humans.
In the Pacific Northwest of North America, the huckleberry plant can be found in mid-alpine regions, often on the lower slopes of mountains. The plant grows best in damp, acidic soil. Under optimal conditions, huckleberries can be as much as 1.5-2 m high, and usually ripen in mid-to-late summer; later at higher elevations.
