Vaccinium corymbosum
Vaccinium vitis-idaea
Every morphological variant of the high-bush blueberry has been named formally at one time or another. At least 25 such taxa have been raised to specific rank; none is distinct throughout its putative range nor has the properties normally associated with biological species, including Vaccinium atrococcum and V. elliottii. See S. P. Vander Kloet (1980) for a complete list of synonyms. Feral populations readily become established wherever cultivars have been planted, e.g., Britain, British Columbia, Japan, Missouri, The Netherlands, New Zealand, Washington, and Wisconsin.

The distribution of Vaccinium vitis-idaea in North America extends from northwestern Greenland at 77° north latitude, south to Connecticut at 42° north latitude, and from 45° west longitude (southern tip of Greenland) west to 170° west longitude (Aleutian Islands); it is rare in Connecticut (not collected since the late 1800s), Massachusetts, Vermont, and Wisconsin. This species has been erroneously reported from New York; it hybridizes with V. myrtillus in northern Europe, producing V. ×intermedium Ruthe. The hybrid might be anticipated in North America, but the two species are not known to occur together anywhere in the flora area.
