Native otocentral and southeastern United States, Ohio buckeye is a popular shade tree and the state tree of Ohio. Its swooping branches with upturned tips are the first to leaf out in spring forming a dense canopy. At first the leaves are bright green but turn dark green by summer and yellow to orange in early fall. The long panicles of greenish yellow flowers give way to light brown 1-2 inch long prickly fruit capsules that contain a single poisonous seed.
