Chinese or European?
Dunstan. It's an American/Chinese hybrid. Supposed to be 15/16 American genetics but I wouldn't bet the house on that. They're not well thought of in the chestnut restoration community, but I'm not trying to save the world so that doesn't much matter to me.
I just want some fresh chestnuts to eat, and it's hard to buy good ones in the store. All I can ever find for sale around here are European and they're always stale and half dried up.
I have quite a few native persimmon trees on my property so no need to buy any. Mrs. Augie loves those things but I'm not crazy about them. I expect they would be very good in sweet rolls or bread but separating the flesh from the seeds and skin is a lot of work so we don't bother.
