Black Walnut

Walnut tree

Description

Black walnut is one of the largest and most valuable trees of Indiana’s forests. Its dark wood is used for fine furniture. The nuts are flavorful, with a unique pungency, and have a hard shell with a nonsplitting husk. Compound leaves have 15 to 25 leaflets. The bark is dark brown and deeply furrowed. The black walnut can reach a height of 100 feet. Hydrojuglone, a chemical found in plant parts, often inhibits growth of other plants in the soil surrounding these trees.
