Black Walnut

The Black Walnut tree is native to the eastern United States but has since spread to include the midwestern states as well and grows mostly in riparian zones.

The Black Walnut is a deciduous tree that grows in both woodlands and fields in moderately moist soil. It can grow to 150 feet in height and has a compound leaf system as shown above.

This tree is grown for several important uses such as:

• Wood for furniture, flooring, and rifle stocks.
• Nuts as food that is high in poly unsaturated fats and protein.
• Hard shells as abrasives in oil well drilling and cosmetics.
• Hull for stains and dyes.
