Juglans nigra

Black Walnut

Walnuts are best suited to large landscapes. Grow these tall, fast-growing trees for their fragrant foliage, elegant stance, and, in some instances, edible nuts. Among the 20 species are the European Walnut (the most commonly grown commercial Walnut), the Black Walnut (an Eastern United States native that is extremely winter-hardy), or the English Walnut. Do not grow other plants nearby because Walnut roots produce growth inhibiting chemicals. Be aware that the English and California varieties of Black Walnut attract aphids, which produce a messy honeydew mixture that dirties patios and cars. In arid summer regions, irrigate slowly and deeply. Prune in summer and fall to shape, and to remove deadwood and suckers. Frost damages young plants.

Wood from its straight trunk is highly prized by woodworkers. Its thick furrowed bark becomes nearly black with age. Harvest the sweet, oily nuts in fall.
