I planted the seeds in the late spring of 2014. The graft was a bench graft in 2/28/2015. It was planted in the field 10/15/2015. That is very quick for an American persimmon but I don't know about the hybrids. This could just be a one-off. I have not seen any persimmons on any of the other ones done at the same time and there is only one persimmon on this tree (bush). Scrolling back to the top of this thread has the details.
Thanks,
Jack
