The majority of hazelnuts grown in the Upper Midwest are open-pollinated hybrids between American (Corylus americana) and European (Corylus avellana). For the most part, no two hazelnut plants in the Upper Midwest are the same. This genetic diversity provides a great opportunity to find and develop locally adapted cultivars.
