Several Walmarts in TN actually had them this past spring (they are from the Realtree Nursery). I don't know if they will get any in next spring. I bought 6 of them, planted 2 of them and potted up the other 4 in larger containers until about a month ago when I set them out. One of them actually had 2 nuts this summer.
I wonder if Wal Mart will have more of these.
