NORTHBLUE NORTHERN BLUEBERRY, this variety grows to around 2–3' tall. Produces an abundance of blooms and it is a prolific bearing plant. These blueberries taste similar to those on wild varieties, but grow larger. When the bush matures, it will yield an excellent 3–7 lbs per season. The plant is great for northern zones too, withstanding temperatures as low as –35°F. Ripens mid June. Northblue Blueberry would make a great pollinator with the Tophat Blueberry Variety hardy in zones 3-7 Pense Nursery, Inc.
