Black walnut trees have highly valued wood with richly flavored, thick shelled, high protein nuts. Their shells are notoriously hard to remove, but that doesn't stop us (and the squirrels) from breaking into the tasty nut inside. Their striking yellow fall color is a joy to see.
The outer hulls contains stain that will darken skin, concrete, and any other porous surfaces. Black walnuts are late to leaf out and early to drop compound leaves. They also produce root chemicals that can inhibit plant growth under its canopy.
