The Upper Midwest Hazelnut Development Initiative (UMHDI) is a collaboration of growers and researchers working to develop a sustainable hazelnut industry in the Upper Midwest. Whether an existing or aspiring hazelnut grower, this website is intended to help keep you informed and connected. Watch the video to learn more about the many projects of the UMHDI. 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. Click here to learn how you, as a grower, can screen your plantings for superior plants and help develop the Upper Midwest hazelnut industry. Copywrite 2009 University of Wisconsin Extension.
