Steve,
I would love to get some of your wild black cherry seeds.
We have a large gardeners group close by in Jacksonville.
We get together for what we call Round Ups, not to be confused with weed killing, where we swap plants seed and garden talk.
I have learned that many plants I grew up with in harsh NW Texas refuse to grow here.
My favorite, Lilacs.
It takes getting use to, but now I would not move back for anything.

We have members there from Pa and they might help.
