A labelling incident some years ago made me mix up my alva, orange dwarf Taiwan starapple and philipinne gold seedlings. I have a friend the esteemed Taiwanese dwarf which he has espaliered over his garage and it is a handsome tree. He just dropped by 5 minutes ago on the way to work to interrogate me on the fruit his tree produced. While it may be the premier starfruit and the cream of the crop he really wanted the Taiwanese one. My geese up-ended pots and pulled out labels and in the rescue mission some were clearly mislabelled. It can take years before such errors can be found out.
I will post a pic when I take one in a few minutes.
