Shellbark Hickory
Carya laciniosa
The largest-fruited native hickory, a bottomland cousin of shagbark with the same shaggy, peeling bark but bigger sweet nuts and stout orange twigs. Slow, deep-rooted, and long-lived; like all hickories it is tap-rooted and best established young rather than transplanted.

Common questions
How is shellbark different from shagbark hickory?
Both have shaggy, peeling bark, but shellbark grows on wetter bottomland sites, has larger leaves and the biggest nuts of any hickory, and shows orange-brown twigs. Shagbark favors drier uplands with smaller nuts.
Are shellbark hickory nuts edible?
Yes — they are sweet and the largest of the hickories, valued by people and wildlife alike, though the thick shells take effort to crack.
