The climate of Minnesota and Wisconsin has made successful blueberry production difficult. But with the introduction of blueberry cultivars with good winter hardiness, minimum upright growth, and large fruit, commercial production of blueberries is possible. Given proper site selection and cultural methods, half-high cultivars offer growers in USDA zones 3, 4, and 5 the potential for long-term---thirty years or more--blueberry production. Half-high blueberries are crosses between high-bush blueberries (Vaccinium corymbosum) and low-bush blueberries (V. angustifolium). The short stature of half-high blueberry plants, along with their inherent cold-hardiness, allows reliable production.
