Want hardy Black Walnuts? Come here and get mine, they grow 2-3 FEET a year even in this dry summer we just had. I can't keep them from growing and sprouts come up from roots that have been getting mowed for the last 3 or more years. I wish I could trade the Chestnut blight for a Walnut blight.
BTW, my American Chestnuts were not phased by the drought but they didn't grow much this year.
