History
Aesculus glabra ranges across the central United States from Pennsylvania west to Kansas and south to Tennessee and Alabama. German botanist Carl Ludwig Willdenow formally described it in 1809. Common names Ohio buckeye and American buckeye reference both its core range and the nut's resemblance to a deer's eye (buck-eye).
It became the state tree of Ohio in 1953, and The Ohio State University athletic teams and mascot carry the name. Indigenous peoples including the Shawnee and Iroquois ground the toxic seeds and mixed them with flour or water to stun fish for harvest—the toxins broke down during processing, making the grain safe to eat after leaching. The species has distinct yellow-green panicles in late April, uncommon among trees, and good orange autumn color.
Leaf scorch in hot dry summers limits its southern garden use. Native Americans traditionally carried the seeds (buckeyes) as lucky charms—a tradition continued today among Ohioans. The Cherokee soaked mashed seeds in streams to stun fish. The 'Buckeye State' nickname reflects the tree's deep cultural importance in the American Midwest.

As Ohio's state tree it carries deep heritage, lending it name to the state's people and university teams. To gift a buckeye is an old, plainspoken gesture: I wish you fortune, and a piece of home to carry with you.
