The tree has a well-formed trunk with high branches and an open oval crown. Its large deciduous leaves are pinnately compound and its nuts are edible, but difficult to harvest due to their thick green covering that stains the skin. The tree is best grown from seed and prefers deep, rich, moist soil. It can be used as a specimen tree, but is not suitable as a street tree due to its messy leaves and fruit. The variety ‘Laciniata’ is the best choice for landscape use. The English or Persian walnut produces the walnut of commerce but is limited in hardiness. The Carpathian walnut is a hardier selection. The scientific name for black walnut is Juglans nigra.
