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 chestnuts. Like all wild-type American chestnut trees, these seedlings are not blight-immune, but they were grown from nuts harvested from some of the best mother trees in America.
