Discussion | Vaccinium macrocarpon is introduced and escaping elsewhere (British Columbia, Oregon, Washington) with respect to its normal range in eastern North America. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
The red, waxy fruits of Vaccinium parvifolium were popular with all coastal Indian tribes and remain so with recreational pickers. The berries are somewhat sour but make excellent pastries and preserves. Commercial use of V. parvifolium is limited; vigorous growth, ease of harvest, and site adaptability provide opportunities.
