Due to its attractive growth, pignuts are beautiful ornamental trees in woodlands and open landscapes. Since the two ranges seem to overlap, the distributions have been mapped together as a Carya glabra-ovalis complex (11). Pignut hickories grow pear-shaped nuts. The deciduous, 8- to 12-inch long leaves create a coarse, oval canopy, and the strong but irregularly spaced branches resist breakage in storms, making it useful as a shade tree. This plant has no children Legal Status.
