Can the hybrids be grafted to American's?
I have no natives growing here (on my place), but there are a few in the county that I know of. They certainly are not common but in the right spot they can grow. My dad planted 8 many yrs ago that have turned into a productive thicket. They drop earlier than I want though so they are not a suitable scion source.
My plan is to order a late dropping grafted variety (they advertise production in 2-3 yrs.), and 20 American seedlings from KS Forestry Service. I figure in a yr or two that I can start grafting from the original grafted tree to the 20 seedlings... or bring in scions from other sources. This would give me at least one producing tree relatively quickly and other producers in 6-8yrs.
Have you had any of your grafted trees start to produce yet? Any reason to prefer any varieties yet?
I would not count on any of the advertised time to fruit with American persimmons. It is not uncommon for trees grown from seed to take 8-10 years to produce their first persimmon. Grafting (American to American) seedlings may cut a couple years off that because the scions from a mature tree have had a hormonal change. However, you are still dealing with a young relatively small root system. The reason grafting native trees works so well is that once a persimmon hit an inch in diameter, they have a well established root system. Combine that with a mature scion and you can get fruit in the 3rd leaf after grafting.
I would say at a minimum, the times listed by nurseries are very optimistic. Perhaps if you get a particularly vigorous tree and it is growing in just the right climate in just the right soils, it could happen. I would pretty much ignore them for planning purposes for wildlife trees. If you get early production, consider it a bonus gift.
Yes, you can graft hybrid persimmons and full oriental persimmons to American rootstock. That is what I did with the Nikita's gift. Asian persimmons do produce fruit much earlier than American trees. I think because these are hybrid, I had a couple of them produce a single persimmon their first year in the field when they were only a few feet tall. Keep in mind that I grew the rootstock from see for a full growing season in Rootmakers on my deck. I over wintered them and brought them in early and woke them up under lights. I then grafted the Nikita's Gift scions to them and kept them all season growing in optimal conditions on my deck. I planted them in the field that fall. It was the next fall that a couple produced one or two persimmons. My guess is that once the root system is limited to my native soils for nutrients rather than the promix with fertilizer, things will slow down.
Yes, the field trees that I've grafted are producing persimmons. When I first started to experiment with this, I was just converting native male trees using scions from native female trees. Here is the thread for that:

The next year, I started with some named variety scions and the third year started trading scions with others. In the second spring, we had big cicada hatch. They hammered my native grafted trees. The new grafting I had done that spring had not leafed out yet so they did not touch it. Some of my second year trees grafted with named variety scions produced in their 3rd leaf. I think because of the cicada setback, the first year trees did not start producing persimmons until the 5th leaf. All in all I'm happy with my persimmons. They were by far the best tree investment for the dollar, but it will probably be several more years until production is sufficient for them to be a significant food source.
Deer seem to eat persimmons with absolutely no preference for variety. In my area, anyway, they will seek out and eat any persimmon. Also keep in mind that bare root trees may be a bit older when you buy them, but when you transplant them, you will get a year of sleep, a year of creep, and finally a year of leap while the root system is reestablishing itself. This pretty much offsets any advantage of buying bigger trees.
I see nothing wrong with your approach except your time expectations may be a bit optimistic. Buying seedlings and grafting them yourself is not a bad plan but you still have the bare-root sleep/creep/leap issue but you can buy them pretty inexpensively. If you are growing other trees with a root pruning container system and already have the setup, growing your own from seed is even more economical. You can grow them by the hundreds, select the best, and cull the rest and end up with very good trees to graft and you don't have the bare-root issue when planting from rootmakers.
In my previous post I included a link to a thread that shows growing them from seed. This thread shows grafting the seedlings:
