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.

Top Shelf is a high chill cultivar that has performed excellently in all commercial trials planted throughout Europe, even in high chill regions where winters are not too cold. It has superb fruit quality that is catching the attention of many European marketers. It is a strong plant, easy to prune, and has high yields at a young stage, mainly due to its very large fruit size.
