Vitis labrusca White Diamond (seeded green/white)

this selection is a Vitis labrusca-type grape, the American slip-skin lineage best known through Concord, with bold foxy-sweet flavor and forgiving garden manners. The fruit is excellent for fresh eating, juice, jelly, and home wine. Vines are vigorous, cold-hardy, and tolerate a wider range of soils and disease pressure than European wine grapes.

Plant Vitis labrusca in full sun on well-drained ground with a sturdy trellis, arbor, or wire system in place from day one, these vines need real support and yearly structural pruning. In the Pacific Northwest, prune hard in late winter while fully dormant, train to a two-arm or four-arm cordon, and thin shoots in spring to keep the canopy open and dry. Mulch lightly, keep summer water steady through fruit set, then ease back as harvest approaches to concentrate sugars.

American grapes are self-fertile and wind-pollinated, so a single vine can fruit on its own. Powdery mildew, downy mildew, and botrytis bunch rot are the main PNW disease concerns, but labrusca-type vines are noticeably more disease-tolerant than Vitis vinifera. Birds and yellowjackets are the biggest harvest competitors, bag clusters or net the canopy as fruit colors. Vines are not strongly deer-resistant and young growth is a favorite browse.

If you're considering native fruiting alternatives that support PNW birds and ecology, look at Vaccinium ovatum (Evergreen Huckleberry), Vaccinium parvifolium (Red Huckleberry), Rubus parviflorus (Thimbleberry), Rubus spectabilis (Salmonberry), or Amelanchier alnifolia (Saskatoon). These provide bird food, pollinator support, and Indigenous food heritage in your landscape.
