About

Carya ovata, commonly known as shagbark hickory, is a deciduous tree that can reach heights of up to 20 meters. Its distinctive bark peels away in large strips, revealing a grey to brown surface. The compound leaves typically consist of five leaflets and exhibit a golden yellow hue in the fall. In spring, the tree produces male catkins that can grow as long as 12 centimeters. The nuts, encased in a thick shell and measuring up to 6 centimeters in length, become edible once fully mature.

About the genus
