Zones: 4 - 9

Zone Map



The Black Walnut Grows in zones 4 - 9
  • Yields a ripened nut crop in early to mid-autumn that consists of three layers: a green, fleshy husk; a black inner shell that is hard, thick and corrugated; and the kernel, which is oily and sweet
  • Begins to bear nuts in 12­–15 years
  • Is prized in the woodworking world for its handsome grain
  • Features pinnately compound, alternate leaves that are 12–24" in length and consist of 15–23 dark green leaflets that are 2–5" long; the leaflets are finely toothed
  • Is self-fertile but requires wind for pollination; plant more than one tree to ensure a better crop
  • Grows in a rounded shape
  • Develops a deep taproot, making it difficult to transplant
  • Can be toxic to certain trees and plants—such as serviceberries, chestnuts, pines, arborvitae, apples, cherries, tomatoes, potatoes, peas, peppers, cabbages, alfalfa, blueberries, blackberries, azaleas, rhododendron, lilacs, hydrangeas, privets, and plants in the heath family—if planted too close

Highlights

Practicality and aesthetics combine in the black walnut to make this species one of the most treasured trees in American history. The valuable dark brown wood is strong with a handsome grain that polishes easily and gleams forever. And the rich, flavorful nuts are enjoyed fresh and retain their flavor and texture during cooking.

Whether you love it more for the stunning wood or the delicious nuts, it is an upstanding tree.
