Special about this tree:

- Foliage is compound leaves, each with 15-23 leaflets
- The large, sturdy trunk produces beautiful hardwood, but the tree is slow-growing.
- Nuts are encased in rough outer shells that turn from green to brown to black in fall. The nut meats are hard to remove from the shell, but are edible.
- Bark is rough, dark and deeply furrowed in diamond patterns.
- Roots produce chemicals that are toxic to many other plants, a means the tree has to keep competitors away.
