I am trying a bunch of new plants this spring; I have hazelnut and witch hazel saplings on order, and I hope to a couple of paw paws as well, In smaller plants, I will try to start some ground nuts from seed.
I planted a bunch of sunchokes in the fall, and hope to have enough to eat as well as leaving some to come back next year.
Ground nuts are actually New England natives, but have been forced out. They are nitrogen fixing legumes similar to peas, but they also produce edible tubers, and have dark pink flowers that attract pollinators-- practically a perfect plant!
Here's info about groundnuts:
