Habit | Plants forming dense colonies, 0.3–6 dm, superficially rhizomatous; twigs yellow-green, reddish green, or reddish brown, terete to somewhat angled, finely puberulent or, rarely, glabrous. | Plants erect, not colonial, sometimes suckering, 10–50 dm; twigs green, angular to terete, usually hairy in lines. |
Leaves | blades green, usually oblanceolate, sometimes obovate or narrowly elliptic, 10–30 × 3–12 mm, margins usually serrulate from apex to at least mid blade, surfaces usually glandular abaxially, usually glabrous adaxially. |
usually deciduous; blade dark green, ovate to narrowly elliptic, 15–70 × 10–25 mm, subcoriaceous, margins sharply serrate or entire, surfaces glabrous or hairy abaxially. |
Flowers | calyx pale green, lobes vestigial, glabrous; corolla white, white with pink striping, or pink, cylindric-urceolate to globose, 4–7 × 3–5 mm, thin, glaucous; filaments glabrous. |

Discussion | 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.
