Narrative

Berry: large; flesh flavor good, pleasing sugar: acid ratio, firm; holds well under refrigeration; processed quality good; skin dark blue, attracive. Plant: low-saturated, 20-30 inches; productive; vigorous; foliage dark glossy green. Brooks and Olmo. 1997. ASHS Press. p. 184.Midseason. Semi-dwarf bush, growing to a height of 3-4 ft. Fruit is large, dark blue, with a 'wild' blueberry flavorNorthblue was released by the University of Minnesota as a commercial variety where productivity of normal highbush cultivars is poor due to cold winter temperatures or inadequate winter protection. Northblue is quite productive for its size producing between 3 and 7 pounds per bush in Minnesota tests. Initial observation here in Oregon indicates a high yield potential in milder climates. For commercial plantings 2 or 3 by 8 foot spacing is recommended. Very little pruning is needed for Northblue the first few years then regular thinning of old wood is recommended. Northblue is suggested for colder winter climates for commercial, U-pick and local farm sales.
