Juglans nigra, commonly referred to as the Black Walnut, stands as a striking deciduous tree known for its valuable timber, flavourful nuts and ornamental qualities. Native to Eastern North America, this tree has a storied history, being prized by early settlers for its wide range of benefits.

Mature specimens of Juglans nigra can grow to significant heights, often boasting a round spreading head, furrowed bark and pinnate leaves. In autumn, the foliage transforms into a radiant display of golden yellows, offering a vibrant contrast against its dark bark. In spring, the tree produces inconspicuous  flowers that mature into round, green fruits, eventually ripening to walnuts. The nuts produced by Juglans nigra are some of he most flavourful of all walnuts, encapsulated within a hard, thick shell that is notoriously difficult to crack, but well worth the effort. Beyond its culinary appeal, the wood of this tree is highly sought after for its dark, dense and durable timber.

The Black Walnut holds ornamental value, lending a stately presence to landscapes with its commanding stature and attractive foliage.
