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.) |
