Kenny Maxfield in Idaho was the NAFEX persimmon group chairman for some time and he had a program of breeding for cold hardiness. He had a lot of seedlings as hardy as you are seeking. He sent seed to many other members to grow and select for hardiness, so there should be some out there. In the meantime, "Meader" persimmon is the main one that is already proven hardy to -30 F. A lot of it depends on the fall weather, though. A fairly long, dry fall will induce greater hardiness than a wet one, or one in which frost comes very early (like, while the fruit isn't fully ripe).

Never mind zone 3. Does anyone have a mature diospyros virginiana that reliably  withstands zone 4 winter temperatures (-29*C to -35*C)without injury?
What minimum temperature has it sustained and withstood?

Hi Jim,

I'm going to place myself out on a limb and give you my best guess as I'm in zone 5b. No, there isn't likely a zone three persimmon. But I'd like to see you try an early bearing variety such as Juhl or Claypool's H-118, a daughter of Juhl. 

Once established D. virginiana (90 chromosome race) may survive your winters but likely you don't have a long enough growing season for fruit to mature and ripen. Even here in central west Indiana (zone 5b) the 60 chromosome persimmon doesn't ripen. I've tried several of them. They survive our winters, and we often get below -10F, but fruit stays green because the growing season ends too soon.

One more thing. You may have better luck establishing persimmon by starting from seed, then grafting.

Jerry

(wild?) persimmon last year and, after an unusually mild Winter, one died
down to the (almost no) snow line and the other died completely.
