Product Description

Walnut, Black

A rugged, deciduous, and mighty giant of a tree, the Black Walnut has been hailed as one of the most scarce and most coveted hardwoods native to North America…


What distinguishes the lovely Black Walnut?

  • Exceptionally strong and dense wood (especially its dark heartwood)

  • Majestic height, towering up to 100 ft.

  • Minimal maintenance required.

  • Large, heavy, harvestable nuts.

  • Dense canopy that provides abundant shade


Keeping up appearances…

Rearing up to an impressive height between 75-100 ft. with a respective 75-100 ft. span, the majestic Black Walnut’s thickly ridged brown branches lift its dense round-crested canopy to the heavens. Juglans Nigra, as it is scientifically classified, belongs to the Juglandaceae family. The species’ leaves are alternate, deep green, and broad. From May to June, the Black Walnut’s yellowish-green catkins bloom in clusters of 2-5, later giving way to brownish-green fruits which are shaped and colored like tennis balls, peeking between the tree’s golden autumn foliage. These large and heavy nuts are fervently consumed by squirrels if not harvested by humans, and they tumble from the Black Walnut in early autumn.


A friendly recommendation.

With a 4-9 hardiness zone rating, this tree thrives in medium well-drained soils and prefers access to direct full sun. Native to eastern North America, the Black Walnut can be found in forests and in open upland areas, reigning as a dominant specimen that has even proven to be allelopathic (its roots produce a toxic substance known as juglone, which drastically interferes with the growth of other nearby plants); if cultivated in a yard or landscape, it’s best planted at a respectful distance from other trees and shrubs. In general, the Black Walnut requires little maintenance.


Awesome tree trivia!

  • The Black Walnut’s wood (especially its dark heartwood) is prized and capitalized for furniture, veneer, gunstocks, and lumber—so much so that these trees are sometimes reported stolen.
  • Since colonial times, this specimen has served as a protective and accommodating ally to our pioneering forefathers, providing strong lumber, ample shade, edible nuts, and even an inky dye that can be drawn from its husks.
  • The Black Walnut’s nuts are actually large and heavy enough to prove hazardous to anyone standing beneath them on a windy day or when ripe.
