The name ‘huckleberry’ is a North American variation of the English dialectal name variously called ‘hurtleberry’ or ‘whortleberry’ (/ˈhwɜːrtəlbɛri/) for the bilberry. In North America the name was applied to numerous plant variations all bearing small berries with colors that may be red, blue or black. It is the common name for various Gaylussacia species, and some Vaccinium species, such as Vaccinium parvifolium, the red huckleberry, and is also applied to other Vaccinium species which may also be called blueberries depending upon local custom, as in New England and parts of Appalachia.
Huckleberry fruits are edible and resemble blueberries (Vaccinium species), to which they are closely related. … The fleshy fruits have 10 small seeds. The common huckleberry (G. baccata) of the eastern United States and Canada is also called black, or high-bush, huckleberry.
