where are you located..I have a standing offer that people can come by and help dig and have them for free here..pm me if you are in Michigan..I'm in central northern part of lower penniinsula..
if you are a long way away though, I suggest if you can't get them, go to a market that sells them and buy some for food quality..and plant those..they generally are going to be a good one to grow in your area..
I suggest planting only one or two per family member..if you want them just for your own use as they multiply like
rabbits
