There was Actually a persimmon growing wild when we acquired the property 10 years ago. I should have paid more attention to what was already growing down there: Blackberry, Grape, Persimmon, Mulberry and asparagus. .I have a couple willow trees in the lowest spot. Pears on Callery are doing ok where water can stand for weeks at a time but, have issue with fungus, bacteria and late frosts. Stone fruit is all dead down there.
