  • Yields a ripened nut crop in the fall; the sweet kernels are covered with a ¼" thick husk and a hard, light brown shell
  • Produces the largest of all hickory nuts; with husk intact, the fruit is 1¾–2½ long
  • Begins to bear nuts in 10–12 years if grown from seed

Highlights

A native of moist bottomlands and floodplains of the United States, the shellbark hickory was once a common sight. Only few stand in nature today, but when you do encounter one, it is a memorable sight. Drooping lower branches. Large yellow-green leaves. Shaggy bark curling up at the ends.

While this nut tree is not very widely planted, you needn’t shy away. It’s a slow grower to be sure, but the long-living shellbark hickory will reward patient tree planters with strong limbs, few natural pests, low maintenance, and large nuts.
