Facts
Look for high-bush blueberry primarily on wetland margins and keep an eye out for the large, juicy blueberries to mature in August, when they are a delight to eat. Second only to low-bush blueberry in economic importance, high-bush blueberry has long been cultivated for its delicious fruit. Bears and many birds, including catbirds, scarlet tanagers, and thrushes, relish the berries. Many ornamental cultivars also exist; old shrubs can take on an interesting, gnarled appearance with a spreading crown.
Habitat
Bogs, fens, forests, shores of rivers or lakes, swamps, woodlands
New England distribution

From Flora Novae Angliae dichotomous key
5. Vaccinium corymbosum L. N
highbush blueberry. Cyanococcus corymbosus (L.) Rydb.; Vaccinium corymbosum L. var. albiflorum (Hook.) Fern.; V. corymbosum L. var. glabrum Gray • CT, MA, ME, NH, RI, VT. Swamps, fens, bogs, shorelines, locally found in upland forests and woodlands. Vaccinium corybosum is a variable taxon, which has undoubtedly led some researchers to consider most of the highbush blueberries as a single species. However, field studies in various parts of the eastern United States consistently show that several morphologies can be distinguished. Therefore, additional highbush blueberry species are here recognized ( V. caesariense, V. fuscatum).
1×5. Vaccinium angustifolium × Vaccinium corymbosum → Vaccinium ×atlanticum Bickn. is a rare blueberry hybrid known from MA, ME, NH. It most resembles plants of V. corymbosum, given its non-colonial habit, but typically is shorter than 1 m at maturity. It is further characterized by leaf blades (25–) 35–65 mm long and corollas (6.5–) 7–9.5 mm long (vs. leaf blades (10–) 15–32 (–41) mm long and corollas 4–6 mm long in V. angustifolium and leaf blades (30–) 38–80 mm long and corollas 5–10 mm long in V. corymbosum). Though F₁ plants do show intermediacy between the two parental taxa, later generation plants tend to become more similar to V. corymbosum (Sam Vander Kloet, personal communication).
Native to North America?
Yes
Sometimes confused with
- Vaccinium fuscatum:
- leaf blades darkening in drying, moderately to densely pubescent abaxially with brown-gray to brown hairs, berry black, not glaucous, and flowers precocious (vs. V. corymbosum, with leaf blades not darkening in drying, glabrous or sparsely pubescent abaxially with white to gray-white hairs, berry blue to dark blue, glaucous, and flowers coetaneous).
- Vaccinium caesariense:
- leaf blades 30–50 mm long, 15–20 mm wide, eciliate, glaucous abaxially, entire, corolla 4–6 mm long, and berry 5–8 mm in diameter (vs. V. corymbosum, with leaf blades mostly 38–80 mm long, 20–30 mm wide, ciliate, green or glaucous abaxially, entire or serrulate, corolla 5–10 mm long, and berry 6–12 mm in diameter).
