Black Walnut, a rapidly growing tree common in the state, is most common in moist bottomlands and open fields, but is found everywhere due to squirrels burying its nuts. Its beautiful, fine-grained, chocolate-brown, relatively lightweight heartwood is the ultimate choice for making solid wood furniture, interior trim, gunstocks, and high-quality veneer. The large nut contained beneath the husks of Black Walnut is round and can be cracked open to expose the bittersweet, oily, and highly nutritious kernel.

A native of the Eastern, Midwestern, and Great Plains regions of the United States, Black Walnut is a pioneer invader tree in open fields or cut-over woodlots, and grows rapidly in youth. It displays an irregular and open growth habit when young, dividing into several spreading branches that give it an upright rounded shape as it matures. Its bold winter texture makes it an outstanding tree to observe during the dormant season. This tree may easily grow to 70 feet tall by 70 feet wide when it is found in the open. As a member of the Walnut Family, it is related to other Walnuts and to the Hickories. The fruit of Black Walnut is composed of an inner kernel, surrounded by a hard corrugated round shell composed of two fused halves. This in turn is surrounded by a thick outer husk that is green when immature (upper right), and yellow-black when ripe. If ripe fruits are picked up, a brown-black dye will easily seep from the moist husk into the skin of your hand, rendering them stained for a couple of days.
