Bluebell Grapes

Bluebell. (Beta x unknown variety). From the University of Minnesota Fruit breeding farm. The blue berries resemble Concord in appearance and flavor, though they are softer and more prone to splitting of the skin. Very productive and vigorous, and hardy to nearly -40 F. Ripens early, at least a month before Concord, even earlier in warmer climates. Some reports of a tendency to iron deficiency chlorosis on alkaline soils, but this isn't a serious problem. Prune to spurs on cordon arms.
