• Northblue

High Chill


Northblue is a great landscape plant and proven producer of quality fruit in cold climates. The fruit has a “wild” taste that makes it excellent for baking or fresh eating. Northblue is a half-high bluberry with wild lowbush ancestry, giving it the ability to survive winter temperatures to minus 35°F, although production is maximized when snow protection is adequate. Recommended for those desiring a higher yielding, cold-hardy variety.
