Tupelo

Fall color of tupelo leaves.

Tupelo or sour gum is a striking pyramidal tree in its youth with horizontal branches growing from a typically straight trunk. As the tree matures it takes on more of an irregular habit. The dark green glossy summer foliage takes center stage in fall when the leaves turn bright scarlet. 

"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."
