- Description
-
Mockernut Hickory is a large deciduous tree that is native to eastern and central USA and can be found in all areas of NC. It is fairly slow growing and will reach heights of 50 to 80 feet tall or more. The crown is rounded and dense. The tree takes 25 years before producing the edible nut but can continue producing for 200 years. It is a strong, straight trunk tree and the wood is used to make various items and for firewood. The wood is mostly white except for the small heartwood, hence the common name.
This tree is adaptable to both sandy and clay loam with good drainage and is drought tolerant once established. It does best in full sun in rich moist soil with lots of room to grow. A deep taproot makes it difficult to transplant.
Use this tree in a park, large yard for shade or naturalized areas.
An important food source for the larvae of both the Banded hairstreak (Satyrium calanus) butterfly and the Hickory horndevil (Citheronia regalis) moth.
Insects, Diseases, or Other Plant Problems: Generally no serious problems. Potential insects are: hickory bark beetle, pecan weevil, borers and twig girdler. Whiteheart rot, anthracnose, leaf blotch, powdery mildew, leaf spot, cankers, catlin blight, crown gall, and scab are occasional diseases.

- Wildlife Value:
- The Mockernut hickory is a host plant for Banded Hairstreak (Satyrium calanus) caterpillars which have one flight from June-August everywhere but Florida where they emerge April-May and many moths including the Luna moth. This is a larval host plant for butterflies and moths. It also supports Hickory Horndevil (Citheronia regalis) which have one brood and appear from May to mid-September. Adult Hickory Horndevil moths do not feed. The nuts are eaten by squirrels, chipmunks and black bears. Fruit is consumed by wood ducks, red-bellied woodpeckers, red fox, squirrels, beaver, eastern cottontail, eastern chipmunk, turkey, white-tailed deer, wild turkey, and white-footed mice. Provide cavities for woodpeckers, black ratsnake, raccoons, and carolina chickadees
