Carya laciniosa, or shellbark hickory, is native to Ontario and ranges throughout North America, specifically from New York and southern Ontario south to Tennessee and Oklahoma. This species is a slow-growing, long-lived tree valued for its sweet, edible nuts. It prefers well-drained, moist conditions, and partial to full sun. Since it requires ample space to thrive, it�s a great choice for larger landscapes. Known for its deep taproot, transplanting can be challenging. Tolerant of occasional flooding and wet sites, it attracts wildlife like birds, small animals, and browsers. Although it faces few serious pest or disease issues, it can occasionally be affected by the hickory bark beetle, pecan weevil, twig girdler, and hickory shuck worm, which may reduce seed production. With its large nuts (largest amongst hickory trees), thick husks, and exfoliating bark, the shellbark hickory can be messy, but its beauty and wildlife benefits make it a valuable addition to plantings. Currently limited availability in the landscape, but with proper seed collection can become more available.
