Phew… That must be a pretty big lake!
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.
Willows are the all star of wetland trees in my opinion. Many are great pollinators too. I wish they also made fruit!
Willows provide early season food for bees and other pollinators so in a way they are still helping support the system that produces your fruit.
The ones I planted were some kind of hybrid from starks. My plan was to take cuttings and plant a wind break / privacy screen. They are actually grafted trees which made me unsure of what they would produce from cuttings.
Native persimmons thrive in the middle of seasonally flooded vernal ponds on Maryland’s Eastern Shore.
Happy to send male pussy willow cuttings your way if interested. They root easily. Super early blooms for the bees.
I would not put pawpaw on this list.
They like generally moist areas but I’m pretty sure they don’t like wet feet. Not only have I read stories about it, but I see evidence in my orchard simply due to clay soils despite the orchard being on a decent slope.
Further, in the wild they are near creeks and rivers but not swampy areas.
