American beech

American beech leaves and beechnuts.

American beech is a large, graceful native tree, excellent for large, park-like landscapes where it has room to spread its wide, low-growing branches. The massive trunk has beautiful silver gray bark; the dark green summer foliage turns a golden bronze in the fall. Leaves typically hang on well into the winter months adding to the seasonal interest. 

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.
