Black Walnut Tree Seeds - Juglans nigra

Black Walnut (Juglans nigra) is a majestic deciduous tree native to North America, prized for its delicious, high-protein nuts and valuable dark hardwood. This long-lived species is as functional as it is beautiful — producing shade, timber, and nutritious food for people and wildlife alike.

The Non-GMO Black Walnut Tree is hardy, drought-tolerant, and well-suited to a wide range of soils. Its deep roots improve soil structure, and its rich canopy provides cooling shade. Ideal for agroforestry systems, nut production, and restoration plantings, it’s a top choice for sustainable growers.
