Black walnut, also known as American Black Walnut, Eastern Black Walnut, American walnut, Eastern american black walnut
Black walnut is a large deciduous tree known for its valuable wood and edible nuts. Special care points include its allelopathic properties, which inhibit the growth of certain plants nearby due to the juglone compound it secretes. It requires well-drained soil and sufficient space to accommodate its extensive root system. Given these considerations, black walnut is generally regarded as difficult to care for in landscape settings due to its specific growing requirements and the potential impact on surrounding vegetation.
