I just started that this year. After having some very tasty Chestnuts, I ordered 5 trees from Perfect Circle, which should arrive next week. 3 will go in the front yard of a rental to replace a ornamental red plum. The other two will go in the backyard of another, replacing two apricots which appear to be dying (they do that a lot for me…).
More recently, I roasted some hazelnuts and decided I liked those a lot as well. So, I got 3 of them from Burnt Ridge. A zig-zag red-leafed one and two of the (relatively) new disease resistant ones from NJ.
I’m going to squeeze the hazelnuts in at home, while the chestnuts go at the rentals. My thinking is that the chestnuts have nice spiney husks to keep the squirrels at bay, while the hazelnuts are more vulnerable and should be grown somewhere I can take more aggressive actions against them.
Wow- persimmons are a no-spray fruit here. I may lose a few to animals, but even there, the losses seem a lot less than apples or peaches. Maybe they are nervous about them after biting into an astringent one.
They are great for pranks if you really don’t like someone 
Actually, I have trouble getting them properly non-astringent and tend to give away 90%+ of mine. Though only to people who assure me that they know how to work with them. One dries them, and I assume the other lets them sit until they are the consistency of pudding.
The other thing I was lacking was seaberries. But, when I ordered the hazelnuts, I threw a few of those into the order and replaced some black currants which had died at a rental (not sure why, but all 3 died at the site- maybe it was excess sun, something that location has compared to other places I’ve grown BC) with them.
I’ve only got one small sweet cherry multi-graft (too much of a pain for too many reasons for me to plant more), but otherwise I think I’ve got just about all the fruits that can be grown outside here (zone 7). Though I’m sure I’ll see something else soon…
