Ohio Buckeye, also known as Texas Buckeye and Horse Chestnut, is a perennial, deciduous tree that typically grows 50 to 75 feet tall, with a broad, oval-rounded crown. Bright green leaves emerge in the spring, maturing to dark green in the summer and yellow in the fall. Its greenish-yellow flowers appear in clusters in mid-spring, followed by the buckeye fruit. This plant grows in full sun to shade and moist, rich, well-drained soils, and though Ohio Buckeye attracts wildlife with its flowers and nuts, note that all parts of this plant are quite poisonous to humans and livestock if ingested.
