Yoderjac: I can't tell by the numbers on the tag. What I do know is that Stark grafted most of them on B118 but can't say for sure. I tried to get this resolved with Stark Bro's so growers like yourself know what they are getting but feel on deaf ears. My suggestion would to purchase Franklins through the Wholesale Division of Stark Bros to assure you are getting the rootstock needed to meet your objectives, but it does have a 50 tree minimum order. For smaller orders, I would check at Cummins Nursery, Wildlife Group, to name a few.
