Bitternut hickory, also called swamp hickory, is a medium or large hickory tree with bitter-tasting nuts. It often grows in low, wet woods but can be found in drier areas. It is found from New Hampshire to Minnesota and south to Florida and Texas. The leaves of this tree usually have seven or nine pointed leaflets. The smooth, round nut has a thin shell that splits into four narrow sections. The plump, white kernel is sometimes eaten by wildlife but not by people. The wood of the bitternut hickory is used in making furniture.
