Author's NotesI grew up in north western Wisconsin (USA), where this tree was absent. I moved to south eastern Wisconsin where the tree is plentiful. Early in my teaching career one of my students offered to me a bushel basket of Black Walnuts. I accepted thinking this should be great eating fresh Walnuts. Little did I know that nuts are tasty but extremely difficult if not almost impossible to crack. Also peeling off the green husk turns your hands walnut color.
