Black Walnut (Juglans nigra)
I'm super allergic to walnuts, so this is one of the few things I won't touch!
Black walnut trees are abundant in the northeastern US. As an allelopathic species, it releases chemicals that give the black walnut an advantage while harming other plants.
Black walnut is edible for animals and humans. You can also tap the trees to get syrup. And, the wood is really popular for wood-working.
Habitat: Deciduous forest

''Juglans nigra'', the eastern American black walnut, is a species of deciduous tree in the walnut family, Juglandaceae, native to North America. It grows mostly in riparian zones, from southern Ontario, west to southeast South Dakota, south to Georgia, northern Florida and southwest to central Texas. Wild trees in the upper Ottawa Valley may be an isolated native population or may have derived from planted trees.
