The black walnut is prized for its dark, richly grained wood and flavorful nuts. Native to the Central and Eastern United States, it has a tall trunk, spreading crown, and deeply furrowed bark. Nut production may begin within a decade but typically takes 20 years for a full yield. Beyond its value as timber and a food source, its hard shells are used in abrasives and its husks as natural dye. The tree produces juglone, a compound that can stunt nearby plant growth, especially in tomatoes. Despite its beauty and value, the black walnut is vulnerable to thousand cankers disease, which often leads to rapid decline and death.
