The Ohio Buckeye, Aesculus glabra, is one of a couple dozen different species of horse chestnut tree. It grows up to about 80 feet tall and is native to the Eastern United States. The five-finger (palmately compound) leaves are nearly as famous in its region as its poisonous, shiny brown nuts. Although the nuts cannot be eaten, they have been used to tan leather (high tannin content) or are dried and strung as beads on a necklace. The name “Buckeyes” is given to all inhabitants of the state of Ohio, along with its state university sports teams. There is also a special candy made of peanut butter dipped in chocolate with a little ring of gold left uncovered at the top — made to resemble the buckeye nut. The Ohio Buckeye is the state tree of Ohio, and the name buckeye comes from one of the area’s early explorers being dubbed “Eye of the Buck” by local Native Americans.
