Identification
Commercially offered blueberries are usually from species that naturally occur only in eastern and north-central North America. Other sections in the genus, native to other parts of the World, including western North America, South America, Europe, and Asia, include other wild shrubs producing similar-looking edible berries, such as huckleberries (North America) and bilberries (Europe). These species are sometimes called "blueberries" and sold as blueberry jam or other products.
The names of blue berries in languages other than English often translate as "blueberry", e.g., Scots blaeberry and Norwegian blåbær. Blaeberry, blåbær and French myrtilles usually refer to the European native bilberry (V. myrtillus), while bleuets refers to the North American blueberry.
Cyanococcus blueberries can be distinguished from the nearly identical-looking bilberries by their flesh color when cut in half. Ripe blueberries have white or light green flesh, while bilberries and huckleberries are red or purple throughout. Bilberries are most often found singularly or in pairs, while blueberries are most often found in clusters.
