Black walnut seeds produce large, long-lived deciduous trees with a strong, upright growth habit and a broad canopy. These trees are well adapted to temperate climates and develop steadily over time into valuable timber and nut-producing specimens. Black walnut performs best in full sun with deep, well-drained, fertile soil and moderate watering during establishment. Suitable for large landscapes, farms, and reforestation projects, it establishes gradually and grows into a substantial tree.
