Shingle oak is native to Illinois and to part of the Chicago region. This tree is not easily recognized as an oak due to an atypical, unlobed leaf. It is not used as commonly as other oak species, but would be valuable as a parkway tree.
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.
