Ohio Buckeye is a tree, and one of five North American species of buckeye. Buckeyes have compound leaves, usually with five leaflets, though in the Ohio Buckeye that number can range as high as eleven. Ohio Buckeye occurs through most of Ohio, Indiana, Illinois, and Missouri, with some populations extending into central Texas and Alabama. Fun fact: the leaves and flowers of Ohio Buckeye, unlike those of other buckeyes, emit a nasty odor.
