General / Habitat
  • Shrub
  • Common to moist coniferous forests, openings, and especially soils rich in decaying wood
  • Low to subalpine elevations.
Key Identifying Characteristics
  • Form: Erect and spreading, up to 2 m tall
  • Leaves: Alternate, deciduous, oval, up to 4 cm long, typically lacking teeth
  • Flowers: Pinkish, urn-shaped and typically longer than broad, generally appear before or with emergence of leaves
  • Fruit: Blue-black berries with a whitish bloom. More flavourful than supermarket blueberries.
Lookalikes
  • Vaccinium alaskaense (Alaskan blueberry)  looks very similar. Most reliable way to distinguish is to take a leaf sample, fold in half along the midvein, and use hand lens to look for scattered hairs on underside of midvein. If it has midvein hairs, it is alaskaense.
    • Other ways: berries of Alaska blueberry emerge after the leaves, oval-leaved blueberry is more highly
      branched and has finer reddish twigs, oval-leaved blueberry has flowers longer than they
      are wide (while Alaska is wider than long), Alaska has fruit stalks enlarged just below berry (while oval is not enlarged)
  • Vaccinium parvifolium(red huckleberry) can also look similar, but has smaller leaves and greener twigs with a less spreading branching pattern, plus bright red berries
Interesting Characteristics
  • Highly regarded by all coastal aboriginal peoples as a delicious fruit
