Only if your microclimate includes a well insulated unheated space to store it in the winter and ample GDD.

If you don’t have a lot of heat units, even PCNA varieties will have residual astringency.
I let my non astringent varieties go soft and then they taste very good.

Forget cold hardiness. No non-astringent persimmon will survive a typical Z5B winter. Instead, pick the earliest ripening variety you can find. Grow it in a pot and store it indoors for the winter, as recommended. Then as noted, you’ll need enough warmth (GDD) over an extended growing season, which you might manage by selecting a great microclimate or, better yet, by creating a greenhouse.
Your biggest challenge, I think, would be managing any late spring / early autumn frosts. If your great micro climate wakes up your trees in April but then there’s a severe frost in May, your tree will probably die. The same tree that survives 0-5 F when fully dormant in February may be killed by 20-25 F when actively growing in May.

Yeah I think this is likely going to be an issue whatever I’m growing, given the climate instability and wild swings (this past spring, in NH, we had 60+F in April and a frost in May…).
