Northblue Blueberry Plant

Northblue Blueberry delivers the wild blueberry flavor of its lowbush parentage in a larger, more productive package than most half-high varieties. The medium-to-large, dark-blue, firm, crisp, juicy berries that ripen in July are genuinely sweet and full-flavored, carrying the complex character that wild blueberry genetics bring to half-high crosses — more depth and interest than standard commercial highbush varieties. Cold-hardy to -30°F, compact at 2–3 feet, and outstanding in containers or in-ground plantings. Introduced in 1983, self-pollinating, with larger crops when planted with Northcountry.

Half-High with Larger Fruit — The Best of Wild Flavor and Productive Size

Northblue sits at a sweet spot in the half-high blueberry world. Where Northcountry leans toward the wild lowbush end of the spectrum with smaller, intensely flavored berries, Northblue produces medium-to-large fruit that delivers the wild blueberry character alongside a more substantial berry size and heavier overall yield. For gardeners who want the flavor complexity of wild blueberry genetics with a more generous harvest per plant, Northblue is the natural choice.

Cold-Hardy to -30°F — A Genuine Zone 3 Performer

The -30°F cold hardiness reflects Northblue’s deliberate development for extreme northern climates. Zone 3 and 4 gardeners who struggle to find productive, flavorful blueberry varieties that actually survive their winters reliably will find Northblue one of the most dependable options available. Introduced in 1983, it has over 40 years of proven northern performance across a wide range of cold-climate conditions.

Plant With Northcountry for Maximum Yield

Northblue is self-pollinating and productive with just one plant, but pairing it with Northcountry — its natural companion variety with matching bloom timing and shared half-high heritage — meaningfully increases berry size and crop yield from both plants. The two varieties together create a compact, highly productive half-high blueberry planting that delivers wild blueberry flavor from a manageable garden footprint.
