Cascade Bilberry

Description

Vaccinium deliciosum is a rhizomatous shrub taking a clumpy, matted form, its tangling stem rooting where its nodes touch moist substrate. It may form expansive colonies. The new green twigs are hairless and waxy and the deciduous leaves are alternately arranged. The thin oval leaf blades are between 1.5 and 5 cm in length while the edges are mostly smooth but may be serrated near the ends. Solitary flowers occur in the leaf axils. Each is 6 or 7 millimeters long, widely urn-shaped to rounded, and pale pink in color. The fruit is a waxy blue or reddish berry with a powdery coating which may be over a centimeter (>0.4 inches) wide. It is said to be particularly tasty. This species can sometimes be confused with Vaccinium caespitosum which grows in wetter areas in the same region. V. deliciosum has a powdery coating on the underside of its leaves, while V. caespitosum does not.
