Description

Botany Dept., NMNH, Smithsonian Institution @ PLANTS General: Heath family (Ericaceae). Native shrubs 2-3(-4) meters tall, crown-forming, forming dense colonies, the twigs warty and yellow-green, glabrous. Leaves deciduous, alternate, simple, narrow to broadly elliptic or ovate, 3.8-8.2 cm long, pubescent at least on the veins beneath, slightly waxy above, the edges smooth and ciliate to toothed. Flowers 8-10 in a cluster, 6-12 mm long, urn-shaped, white, with 5 petals. Fruits berries are 5-12 mm wide, blue to blue-black and many-seeded. The common name refers to the relatively tall stature of these plants. Variation within the species: The highbush blueberry complex is highly variable and includes diploids, tetraploids, hexaploids, and various hybrid combinations. Recent studies (Vander Kloet in 1980 and 1988) have recommended treating the complex very broadly, using only the single name V. corymbosum, but not all authors have accepted that (for example, see Uttall 1986, 1987). As treated in the PLANTS database, the complex includes a group of interrelated species that have generally been recognized as “highbush” blueberries – these species* (or hybrids), with synonyms, are listed below. * Vaccinium X atlanticum Bicknell * Vaccinium corymbosum L. synonym: Vaccinium constablaei Gray * Vaccinium formosum Andr. synonym: Vaccinium australe Small * Vaccinium fuscatum Ait. synonym: Vaccinium arkansanum Ashe synonym Vaccinium atrococcum (Gray) Heller synonym Vaccinium fuscatum Aiton *Vaccinium simulatum Small *Vaccinium virgatum Ait. synonym: Vaccinium amoenum Aiton synonym: Vaccinium ashei Reade Highbush blueberry (V. corymbosum) hybridizes with one of the “lowbush” blueberries (V. angustifolium Ait.). Hybrids used in commercial fruit production are V. corymbosum X V. darrowi (southern highbush blueberry), (V. arboreum X V. darrowi) x V. corymbosum (pollen donor), and southern highbush blueberry hybrids X V. simulatum. Distribution: Widespread in eastern North America, from Nova Scotia, New Brunswick, Quebec, and Ontario, Maine to Wisconsin, southward to South Carolina and Georgia and along the Gulf coast to Arkansas, Louisiana, east Texas, and Oklahoma. It has been introduced outside of its natural range for commercial berry production in Wisconsin, Washington, British Columbia, and New Brunswick. For current distribution, please consult the Plant Profile page for this species on the PLANTS Web site.

Adaptation

Highbush blueberry grows best and most commonly in moist or wet peat of moderate to high acidity – in and around marshes, swamps, and lakes, often with extended flooding, as well as on floodplains, sheltered slopes, and ravines. It also occurs in drier areas – dunes and barrier beaches, rocky hillsides, oak woods, and pine woods. It occurs as a dominant or co-dominant on Appalachian "heath balds." All of these are more or less open sites, and because of its shade intolerance, highbush blueberry can be eliminated as shading increases with overstory cover. Flowering (February-)March-June, sporadically in the southern portion of its range; fruiting (April-)May-October, about 62 days after flowering.

Establishment

Highbush blueberry produces abundant fruit every year. Bees are the primary pollinator. The seeds may be widely dispersed in bird and mammal droppings, but germination success can be reduced up to 15% after passing through an animal gut. In the southern portion of its range, highbush blueberry seeds have thick seed coats and require cold stratification before germination. Those from northern regions produce thinner seed coats and germinate in the autumn after dispersal. Some reports describe vigorous sprouting from the root-crown in highbush blueberry after top-kill by fire or disturbance, while others note that sprouting is uncommon. This perhaps reflects the variability (and perhaps the taxonomic uncertainty) that exists within the species complex. Plants also have been noted to occasionally produce root sprouts 1-2 meters away from the parent.

Management

Seeds or cuttings can propagate plants of highbush blueberry. Ideal soil for cultivation is moist, high in organic matter, highly acidic (4.5-5.5), and well drained. The plants grow in full sun to partial shade, but those in open sites produce more flowers and have brighter fall foliage color. Highbush blueberry (V. corymbosum) is self-fertile, but cross-pollination increases fruit set and results in larger, earlier berries with more seeds (see Agriculture Western Australia 2000). Other species of the complex are partially or completely self-incompatible.

Description

Botany Dept., NMNH, Smithsonian Institution @ PLANTS Highbush blueberry is a native, upright, 6-12 feet tall, crown-forming shrub. The common name refers to the relatively tall stature of these plants. Twigs are yellow-green (reddish in winter) and covered with small wart-like dots. Leaves are deciduous, alternate, simple, elliptic or ovate, 1 to 3½ inches long and slightly waxy above with pubescence (hairs) at least on the veins beneath. The white or pink-tinged flowers are small and urn-shaped with 5 petals, and occur 8 to 10 per cluster. Flowering occurs February to June, sporadically in the southern portion of its range; fruiting occurs April to October, about 62 days after flowering. Fruits are ¼ - ½” blue-black berries with many seeds. In the PLANTS database, plants known as “highbush” blueberries are actually a group of interrelated species. Hybrids are often used in commercial fruit production.

The most common native habitat is in moist or wet peat of moderate to high acidity – in and around marshes, swamps, lakes and flood-prone areas. V. corymbosum also occurs in drier areas such as dunes and barrier beaches, rocky hillsides, oak woods, and pinewoods.

Non-selected materials for conservation use are also available from nurseries.
