Discussion

Vaccinium hirsutum is uncommon (but not threatened) in Tennessee, rare in North Carolina, and probably extirpated in Georgia.

(Discussion copyrighted by Flora of North America; reprinted with permission.)

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.
