The Eastern Black walnut (Juglans nigra) is a species of flowering tree in the hickory family, Juglandaceae, that is native to eastern 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. Isolated wild trees in the Upper Ottawa Valley may be an isolated native population or may have derived from planted trees.
Black walnut nuts are shelled commercially in the United States.
