About
A towering eastern North American hardwood whose roots and fallen husks leach juglone into the soil — a natural toxin that kills tomatoes, apples, and most garden plants within a 50-foot radius. Its deeply wrinkled nuts are prized for baking, but cracking the iron-hard shell typically requires a vice or a hammer.
