Hybrid Chestnuts (Castanea spp.)

Chestnuts are essentially corn that grows on trees! The Hybrid Chestnuts (Castanea spp.) are a solution for those looking to cultivate chestnut trees with improved resilience and productivity. Originating from genetic stock sourced from Minnesota, Oregon, and Ontario, these hybrids are specifically bred to thrive in the unique conditions of Southwest Wisconsin. They are the only chestnut varieties that reliably produce nuts in this region, making them an excellent choice for local growers. Our breeding goals focus on achieving high yields at an earlier age, ensuring pest and disease resistance, and promoting suitability for low-input operations. While the nuts may not be as large as those of the Chinese chestnut, many of these hybrids will begin to flower as early as their fifth year, providing an earlier harvest. It’s important to note that some hybrids may be susceptible to chestnut blight, depending on the expression of their American genetics. This careful breeding process aims to
