Habit | Plants forming extensive colonies, 0.7–2 dm, rhizomatous; twigs green, angled, glabrous; ultimate branches compact, often forming broomlike clumps or tufts. | Plants extensively mat-forming (often by layering), with erect branches from lateral buds, rooting and/or swelling into woody burls at nodes; twigs of current year reddish green, terete, finely hairy, not verrucose. |
Leaf | blades pale green abaxially, elliptic, lanceolate, or ovate-lanceolate, 7–11 × 4–6 mm, margins finely serrulate, surfaces glabrous. |
blades dark green, elliptic to obovate, (10–)12–15(–39) × (4–)5–7(–24) mm, coriaceous, margins ± entire, surfaces glabrescent. |
Pedicels | 0.1–0.3 cm. |

Discussion | The soft, tart, bright red berries of Vaccinium scoparium, to 6 mm diameter, have fair to good flavor and were gathered and eaten raw by the Kootenay, Okanogan, Shuswap, and other Indian tribes. Harvesting was probably done using wooden or fish-bone combs. Small fruit size, low yields, and difficult harvesting make commercial prospects for V. scoparium questionable.
