A cross of American Chestnut (C. dentata), Chinese Chestnut (C. mollissima) and Japanese Chestnut (C. crenata). It has the American Chestnut’s tall timber form along with large, sweet nuts. ‘Sleeping Giant’ is resistant to Chestnut Blight caused by the fungus Cryphonectria parasitica. The trees we offer are seedlings from a ‘Sleeping Giant’ tree and may vary somewhat from the parental tree. Plant two trees to enable cross-pollination for nut production or a ‘Sleeping Giant’ seedling and any other variety of Chestnut we offer.
