Hi Rick! I’d recommend checking https://www.coldstreamfarm.net/product/persimmon-diospyros-virginiana/
and Persimmon - Seedlings - Pikes Peak Nurseries
We use both at work and I can recommend both. I prefer Pikes Peak because they are local for me (Indiana County) but their website is lacking, so I highly recommend calling them to place an order. They are super friendly.
I would try England’s Nursery www.nuttrees.net for an impressive selection of persimmons. They might not have as much this late in the order season but I’d ask. Cliff is on the forum as @KYnuttrees
