Habit | Plants forming small clumps to extensive open colonies, 0.5–15 dm, rhizomatous; twigs green, sometimes glaucous, ± terete, rarely angled, usually glabrous, rarely hairy along veins or puberulent. | Shrubs, erect, (3–)4–12(–40) dm, rhizomatous, (twigs of previous year not verrucose). |
Leaves | blades usually glaucous, obovate, oblanceolate, or, rarely, elliptic, 17–35 × 9–17 mm, margins usually serrate for at least distal 2/3, surfaces usually glabrous, eglandular or, rarely, glandular throughout, often glandular-hairy along midvein. |

Discussion | Vaccinium deliciosum produces especially flavorful berries. Research at the University of Idaho and Washington State University identified 31 aromatic flavor compounds in the fruits. Despite its outstanding flavor and large fruit size, it is harvested less than is V. membranaceum because it has a smaller range and is less abundant there than its black-fruited congener. Also, like V. membranaceum, V. deliciosum is native at higher elevations and can be difficult to grow at low elevations. Although rhizomatous, V. deliciosum has a dense root system and transplants easily. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
The flowers of Vaccinium pallidum are visited primarily by Andrena carlini Cockerell and Bombus spp. This species occasionally hybridizes with V. angustifolium, yielding V. ×dobbinii Burnham. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
