Content Detail

The Ohio buckeye is a neatly rounded tree with low, sweeping branches and dense foliage that provides deep shade. It is one of the first trees to leaf out in the spring. Its name comes from the ‘buckeyes,’ a small, dark brown nut with a light patch resembling the eye of a deer, which grows inside a rounded prickly fruit capsule. This species is susceptible to leaf blotch. 

This species is native to the Chicago region according to Swink and Wilhelm’s Plants of the Chicago Region, with updates made according to current research.
