Facts About

Ohio buckeye superficially resembles horse-chestnut (Aesculus hippocastanum), with its showy spires of white flowers and palmate (hand-shaped) leaves, but its flowers have only 4 petals, not 5. Its wood is used in making boxes, muscial instruments, and flooring. But beware: even though some pioneers carried buckeye seeds to prevent rheumatism, its seeds and young leaves are very poisonous.
