Always and I sort of shout to the world right now, use Northern persimmon seedlings Diospyros virginiana - NORTHERN SOURCED if you’re gonna sell them or trade plants with friends that you may not of planned on doing. Southern American persimmon seedlings are fine for the southern folks as rootstocks or wildlife plantings, but they are not fine for the majority of the country.
Southern seed, grows a rootstock or wildlife tree that in zones 6 and colder dies back to the ground all the time and always kills a graft. If you’re ever in doubt of the seed source/provenance of your trees, ask.
Also, Northern seedlings do just the same as southern seedlings for the south.
