Black Walnut

Description

One of the largest and most valuable trees of Indiana’s forests. Its dark wood is used for fine furniture. Nuts are flavorful with a unique pungency, and have a hard shell with a non-splitting husk.

Hydrojuglone, a chemical found in plant parts often inhibits growth of other plants in the soil surrounding Black Walnut trees.
