The Black Walnut Tree not only provides food for animals, but also walnuts for people. They tend to grow to about 100 to 150 ft. high. Black Walnut trees are prized for their heartwood because of its deep color, heavyness,strength and because it finishes very well. They are fairly rare in the U.S. Because we live on a farm, this tree must be kept out of the fields and away from the horses because a toxin in its leaves called juglone can make them sick.
