Northland is a half-high blueberry cultivar developed by Michigan State University for improved cold hardiness in northern climates. It is a hybrid between highbush blueberry (Vaccinium corymbosum) and lowbush blueberry (Vaccinium angustifolium), resulting from the cross Berkeley × 19-H (lowbush × Pioneer seedling). The cross was made in 1948, selected in 1952, and introduced in 1967 by Stanley Johnston and J. E. Moulton. Bluehaven is a sister cultivar from the same breeding program. Plants typically reach 3–4 feet in height at maturity with a vigorous, moderately spreading growth habit. With severe pruning of horizontal branches, plants may reach 5–6 feet. Fruit ripens around July 7. Yields are consistently high, averaging 15–20 pounds per mature bush. Fruit is small to medium in size, averaging approximately 136 berries per cup, and is borne on long, loose clusters. Berries are dark blue with moderately firm flesh and a medium picking scar when harvested soon after ripening. Flavor is excellent, combining the rich, wild taste of lowbush blueberries with the size and productivity of highbush types. Harvesting can be done by hand or mechanically. Northland is considered one of the most cold-hardy commercial blueberry cultivars and is rated to USDA Zone 3. Its low stature allows plants to benefit from insulating snow cover in cold climates, and its flexible, limber branches are less prone to breakage under heavy snow loads. While not immune to snow damage, it has demonstrated superior survival in regions with prolonged snow cover. Blossoms tolerate light frosts, and the cultivar has performed well throughout northern regions of the United States and Canada. Northland is classified as an early midseason cultivar. In northern growing regions, harvest typically begins in early August and continues through the month. Plants are extremely productive, making this one of the highest-yielding cultivars available. The fruit freezes well and holds up well in culinary uses due to its high flavor intensity. Smaller berries are especially well suited for baking applications such as muffins and pancakes. The fruit is well suited for U-pick operations, fresh markets, and processing. Developed specifically for Northern Michigan conditions, Northland adapts exceptionally well to sub-zero temperatures and harsh winters. Ornamental value is also high. The low, spreading growth habit makes it attractive in the landscape. Foliage is dark green during summer, turns vibrant orange-red in fall, and is accented by yellow stems in winter. USDA Zone: 3-7 Mature Size: 3-4' tall by 5-6' across Sun: Full Sun Ripening Time: July Pollination: Another blueberry bush nearby is required for pollination
