Carya tomentosa
Overview
The Mockernut Hickory is a large native hardwood tree known for its strong wood, tough nuts, and exceptional durability. Common throughout the forests of West Virginia and the eastern United States, it is a characteristic species of upland hardwood forests and is often found on ridges, slopes, and well-drained sites.
Named for its thick-shelled nuts, which contain relatively small kernels compared to other hickories, Mockernut Hickory is valued for its wildlife benefits, high-quality wood, and contribution to forest diversity. Mature trees develop broad crowns and rugged bark that make them distinctive features of the landscape.

- Yellow to golden-brown fall color
- Leaf undersides often covered with fine hairs
Bark
- Gray to gray-brown bark
- Develops interlacing ridges and furrows
- More tightly ridged than Shagbark Hickory
- Mature bark does not peel into long strips
Flowers
- Produces male and female flowers in spring
- Male flowers occur as drooping catkins
- Female flowers appear in small clusters near branch tips
- Wind-pollinated
Fruit
- Round to oval nuts enclosed in thick husks
- Husks split open when mature
- Nuts ripen in autumn
- Kernels are edible but difficult to extract

- Mature spread of 30 to 50 feet
Native Range
Mockernut Hickory is native to eastern North America and occurs throughout West Virginia. It is commonly found in upland hardwood forests, dry slopes, ridges, and well-drained woodland sites.
The species is particularly well adapted to upland environments and often grows alongside White Oak, Black Oak, Scarlet Oak, and other hickories in mature Appalachian forests.
Ecology and Wildlife Value
Mockernut Hickory is an important wildlife tree.
Its nuts provide food for:
- Squirrels
- Chipmunks
- White-tailed deer
- Black bears
- Wild turkeys
- Various songbirds
The tree also supports numerous native insects and provides nesting and shelter opportunities for wildlife. Because hickory nuts are rich in fats and nutrients, they are an important food source for many species preparing for winter.
Human Uses and Cultural Significance
Mockernut Hickory produces some of the strongest and toughest wood of any North American hardwood.
The wood has been used for:
- Tool handles
- Ladder rungs
- Sporting equipment
- Furniture
- Flooring
- Agricultural implements
- Firewood
Like other hickories, the wood is highly valued for smoking meats because of its distinctive aroma and long-burning qualities.
Although the nuts are edible, their thick shells and relatively small kernels make them less desirable for human consumption than those of some other hickory species.
Mockernut Hickory at Marshall University
Mockernut Hickory contributes to the diversity of the Marshall University Arboretum by representing one of West Virginia’s characteristic upland forest trees. Its compound leaves, hard-shelled nuts, and rugged bark provide opportunities for visitors to compare it with related species such as Shagbark Hickory and Pecan.
As a West Virginia native species, Mockernut Hickory helps illustrate the ecological richness of Appalachian hardwood forests while providing wildlife habitat, shade, and educational value throughout the campus landscape.
