The Ohio Buckeye Aesculus glabra is the state tree of Ohio and an original term of endearment for the pioneers on the Ohio frontier, with specific association with William Henry Harrison. Subsequently, the use of the term for the Ohio State University sports teams made the term a widely known title for any graduate, or indeed, any Ohioan. Ironically, the world-record Ohio Buckeye tree is located in Kentucky, not Ohio, and as a consequence, there has for some time been a reward offered for anyone who discovers an Ohio Buckeye in Ohio large enough to become the new champion.
Of small but interesting note is the Buckeye confection - made to resemble the tree's poisonous nut - which is made by encasing a dollop of peanut butter with milk chocolate. These can be found throughout Ohio, especially as a treat during Christmas time.
