I did a root grafting experiment (for an upcoming blog), and have a resultant small persimmon tree to give away. The rootstock is seedling American persimmon, and the scion, which will be the fruiting part of the tree, is a non-astringent Fuyu with fruits about three inches across, which has been reliable in my yard.
Basically, the experiment was on how to create usable rootstock when you can't find any to buy. I took three sections of persimmon root, and used those as the stocks. I directly grafted on twigs. One died, one "took", and the one that took plus another one put up adventitious shoots directly from the root. From the good one, I assume you would rub off the adventitious shoots but you could plant the other one and graft onto the shoots when they get big enough.
One thing people don't seem to realize when starting small persimmon trees is they are native to places, like eastern North America, where it rains all summer. So, you have to water them like crazy the first couple years. When they get bigger, they develop a dense shade that keeps down completing grass, plus they sink a deep root system. To get any satisfaction out of this thing, you should be committed planting it in the ground, no grass or weeds, and watering it well all summer the first few years. Please don't even think about growing it in a pot. I may as well chop it up with a hoe right now and save us both the trouble.
If interested, write me directly by email <firstname.lastname@example.org>. I would prefer you take the whole experimental setup (see photos), because I have all the information from it I need. I can put it out on my front porch for you, no contact needed.
Thanks for doing this Rick. You are very generous. I probably have too many American persimmons, as they are one of my favorite fruits. I appreciate what you do for the community.
