Description
Duke is the blueberry for people who want to start picking early and keep those berries in good condition after they come off the bush.
It ripens near the beginning of the northern highbush season, yet its flowers open relatively late. The berries are firm and their flavor holds unusually well in storage, making Duke especially useful for families who pick more than they eat in a day or two.
The flavor is mild and clean rather than intensely aromatic. Pick the berries fully ripe and Duke gives you pleasant fruit that travels, refrigerates and freezes exceptionally well.

Additional Notes
