The Butternut White Walnut kernal is easily separated from the shuck. Butternut or White walnut, ˜Juglans cinerea", is genetically closely related to the black walnut, Juglans nigra, that forms oval shaped nuts, with a thick corrugated shell, 2 inches long with white kernels; richly flavored and preferred by many people to have a superior flavor over other cultivars of walnuts.

The name, 'Butternut' is accurate in describing the flavor of the kernels of the Butternut (White) walnut. The oval-shaped walnut cracks into oily, sweet tasty kernels that have a distinctive aromatic flavor. The kernels crack out whole, without splintering, and the tree grows large and bears large amounts of walnuts.
