The Ohio Buckeye is the seed of the Aesculus glabra tree, native to the Midwestern United States. It is typically round and smooth, with a light brown color and a darker spot on one side. The nut is not edible for humans, as it contains toxic compounds, but it is a food source for wildlife. The Ohio Buckeye tree can grow up to 100 feet tall and is known for its distinctive palmate leaves and yellow-green flowers. It is the state tree of Ohio and is often associated with the state's sports teams, particularly the Ohio State Buckeyes football team.
