The wood of the American Black Walnut Tree is hard, beautiful and durable. The gnarled wood of the Black Walnut Tree stump was found to be especially beautiful, desirable and expensive and was made into antiques that today are so pricey that only museums can afford them, and it is called "Black Walnut Burl". The American Black Walnut Trees are very prolific and in the Fall, large clusters of Black Walnuts form and grow in size and then fall to the ground for easy harvesting.
When the hull of the Black Walnut turns brown, or black that means the walnut is mature, cured-out and ready to harvest. When Black walnuts fall to the ground, they are covered with a green porous husk that can easily be removed either by scraping it off or by boiling the green-black walnut hulls in water.
