Description

Black Walnut (Juglans nigra) is one of North America’s most iconic legacy trees—celebrated for its dark, fine‑grained heartwood, bold architecture, and centuries‑long lifespan. Its broad, airy canopy casts dappled shade through summer, while long compound leaves shift to clear yellow in fall. In winter, the deeply furrowed bark and strong branching give the tree a powerful, sculptural silhouette.

This species thrives in full sun and deep, fertile soils, developing a straight trunk and strong central leader when grown with space. Its nuts support wildlife, and its timber is among the most valuable of any native hardwood. Black Walnut is a defining species for restoration plantings, large homesteads, and long‑term legacy landscapes where permanence and character matter.
