Blue Jay is a blue hardy grape from the Minnesota State Fruit Breeding Farm. The Daniels catalog lists it as Minn. No. 69 and calls it probably the best blue hardy grape from that program. This places it among the mid century Minnesota introductions selected for cold region growing, not as a general table grape for warmer districts. [S1]
Daniels describes Blue Jay as vigorous and heavily productive. The grapes are said to be large and high quality, borne in compact, medium sized bunches. The source does not give a fuller flavor note, season, or keeping description, but it presents Blue Jay as a grape of real quality rather than a novelty. [S1]
The clearest practical point is where it was recommended. Daniels recommends Blue Jay for all parts of Minnesota, which is the strongest hardiness evidence here. The same listing also advises planting it with other varieties for pollination, a useful note for growers planning a vineyard row rather than a single vine. [S1]
Blue Jay matters as part of the Minnesota hardy grape line that nurseries were promoting for the Upper Midwest in 1950. In this source it appears beside other named hardy grapes and is priced higher than Concord, which suggests it was treated as a newer or more specialized breeding farm introduction. [S1]
