Despite the specificity of its common name, the Ohio buckeye is found growing naturally from Pennsylvania through eastern Texas. Among the American horsechestnuts represented in the SIU arboretum, its maximum size is typically much smaller than the yellow buckeye and larger than the red buckeye and its flowers are less conspicuous than both. So with apologies to Ohio State fans, we are left wondering how this particular species warrants mascot status.
