The Dunstan chestnut (Castanea dentata x mollissima) is a tried and true hybrid between a rare blight resistant American chestnut specimen and several Chinese chestnut cultivars, producing an abundant crop of consistently large and sweet tasting chestnuts with a nutritional profile similar to that of corn. These dual purpose trees also provide excellent timber, growing to a height of 40-60 feet. They require little or no maintenance once established. Transplant after the last frost in your area, protect them from deer, and rest assured knowing you've created a source of food security and stability which will stand for centuries.
