Description

Pignut Hickory is a deciduous tree that may grow 80 to 90 feet tall. The leaves are alternate and pinnately compound with 5 (rarely 7) leaflets. The bark on young trees is smooth with shallow cracks. As the tree ages, the bark develops flat, sharp-edged ridges that form diamond and x-patterns. Very short, yellow-green, slim, cylindrical flowers cluster mature at the end of branches in spring. The tree produces a nut which matures in the fall.

Fire Risk: This plant has a low flammability rating.

Seasons of Interest:

Insects, Diseases, or Other Plant Problems:  There are no serious insect or disease problems. Hickory bark beetle, pecan weevil, borers and twig girdler can be problems in some areas of its range. White heart rot, anthracnose, leaf blotch, powdery mildew, leaf spot, cankers, catkin blight, crown gall, and scab are occasional diseases. Large trees can produce considerable litter through twig, leaf, and fruit (nut) drop.
