Yep, not going to find it in FL. That was my quest last year. I think Frankie's in Hawaii sells budwood from it. I bought budwood from montoso gardens but it may have been Z2. None of mine took. Frankie's did not have any grafted trees last year but maybe check with them now. Grafting them is supposed to be pretty tough. Especially if the scions are not super fresh. I gave up and bought a big seedling from benders grove that is flowering now.
