Black Walnut Facts
Black Walnuts (Juglans nigra) are large hardwood trees. Walnuts are a very important food source for rodents. Their shells are extremely hard; squirrels are one of the few animals that possess enough jaw strength to break walnut shells. They are also harvested commercially; in fact roughly 150 different grades of walnuts exist. The wood is dark, extremely hard and has been traditionally used of gunstocks. Juglones, which is a natural herbicide, occurs naturally in the leaves and bark. That’s why you don’t often see undergrowth under black walnut trees.
