While supplies last, order American chestnut seedlings, from seeds gathered in one of America's leading conservation orchards. Our orchard mother trees were deliberately inoculated with 3 versions of chestnut blight. Those that survived, many over 30 years old, produced nuts for your seedlings. These are 100% American chestnut trees, and many are over 30 years old. Like all wild American chestnut trees, these seedlings are susceptible to blight, but they were grown from nuts harvested from some of the best mother trees in America.
