Best planted in early spring after your last frost, or in fall before the ground freezes, depending on your climate.

Small, sweet-tart black grapes, good fresh and traditionally used for jelly and raisins by Indigenous peoples of the region. Closely related to V. californica, with which it hybridizes readily where their ranges overlap.
