About plant names...

Vaccinium is a hardy genus of shrubs that produces many of the berries we love to eat: bilberries, blueberries, whortleberries, hurtleberries, huckleberries, cranberries, lingonberries, dangleberries, and cowberries among them. Many species are cultivated now. Bears, birds, and many other animals also enjoy these fruits. Vaccinium taxonomy is bewildering, in part because they hybridize freely.

Identification: Plants are mostly deciduous perennial shrubs (a few are evergreens), some only a few centimeters high, others a meter or more, with tough, flexible branches. They seem to hunker down, adjusting to the often exposed locations they inhabit, flourishing where few species can. Some prefer bogs; others acidic, sandy soils or woodlands. They have shiny, elliptic leaves and flowers that are usually urn-shaped, and about the same size as the berries. Berries vary in size from ⅛-½" (3.2-15 mm) in size, and may be blue, red, or black.

Below are some of members of the Vaccinium genus, along with some similar-appearing members from Gaylussacia:

Gaylussacia dumosa
Common Name

Black Huckleberry


Dwarf Huckleberry
Plant 12-36" (30-91 cm) in height, with stiff branches that are light brown or greenish when young, changing to gray or black with age. Shrubs are found in colonies. These low evergreen shrubs are 6-18" (15-45 cm) high. 12-30" (30-75 cm) in height, and heavily branched. Young twigs are covered with short, curly hairs.
Flowers Pink, about ⅜" (9.5 mm) in size, and urn-shaped, in racemes. They bloom from May to July. White or pinkish, urn-shaped, about ⅛" (4 mm) in size, appearing from May to June. Bell-shaped, cream-colored, tinged with pink, appearing in June.
Leaves Oval, becoming orange/red in the fall. Leaves are coated with gold-colored resin glands. The resin can be seen by rubbing the leaves between your fingers, or on a piece of paper. Leaves resemble boxwood leaves. They lack the resin glands found in other huckleberries, and are dark, glossy green, becoming bronze-colored or reddish-purple in the fall. They are ovate, with crenate or serrulate edges and leaf petioles (stems) ¹/₃₂-⅛" (0.5-3 mm) long. 1" (2.5 cm) long, leathery, and obovate to elliptic.
Fruit Berries contain 10 seeds, fewer than blueberries. Resembles blueberries, but with fewer, larger seeds. They are about ⅜" (1.2 cm) in size. Berries are about ¼" (8 mm) in diameter, each with 10 seeds, fewer than for blueberries.

Highbush Blueberry

Blue Huckleberry

Black Highbush Blueberry
Plant Said to be up to 12' (3.7 m) in height, though I have never seen one larger than 4' (1.2 m) high. Deciduous shrubs are less than 12" (30 cm) high, forming sprawling mats. Shrubs are perennials, reaching 11' (3.5 m), with brown bark.
