Black walnut, or Juglans nigra, is one of the premier trees of the North American forests. It is large and majestic, reaching as high as 150 feet, though, when grown in the open, it is usually at 75 feet with a spread of 75 feet. Black walnut has brown-black bark and attractive, glossy, dark green pinnate leaves which turn bright yellow for autumn. In late spring and early summer inconspicuous flowers are produced which are followed in autumn by one of the most valuable nuts grown in the world: walnuts. The Black Walnut is considered to be the best tasting of the walnuts but also the hardest to crack due to the thick hard husk and shell. The nut is popular as flavoring and the hard shell is ground to make an abrasive. The wood is highly prized for furniture and cabinet making and hardly a great house in England exists that doesn't have some piece of Black walnut furniture.

Black walnut may be too large for most urban gardens but it would be a wonderful specimen tree for a large garden, park or university common. It does well across most of North America and the British Isles.

It likes full sun where it will grow straight and upright without any droop. It has a coarse texture and grows at a moderate pace..

A notable cultivar is 'Laciniata; which has beautifully dissected leaves.

And there is the walnut’s cousin, the Pecan, Carya illinoiensis, as useful as it is handsome.
