Ohio Buckeye (Aesculus glabra): A Native Shade Tree

The Ohio buckeye (Aesculus glabra) is a beloved native tree of the Midwestern United States, celebrated for its showy spring flowers, distinctive palmate leaves, and glossy brown nuts. As the state tree of Ohio, it holds cultural significance and provides valuable shade in parks and large landscapes.

Seasonal Interest

In spring, the tree produces upright clusters of creamy yellow-green flowers that attract pollinators. The foliage emerges bright green, maturing to a deep green in summer, and turns a striking pumpkin-orange in autumn. The nuts, encased in a spiny husk, ripen in fall and are a favorite of wildlife, though they are toxic to humans if eaten raw.

Taxonomy and Synonyms

Growing Conditions

Ohio buckeye prefers moist, well-drained soils and thrives in full sun to partial shade. It is adaptable to a range of soil pH but does best in slightly acidic conditions. The tree grows 20-40 feet tall with a rounded canopy, making it an excellent shade tree for large yards. It is relatively low-maintenance but can be susceptible to leaf blotch and powdery mildew in humid conditions.

Whether planted for its ornamental value, wildlife benefits, or state pride, the Ohio buckeye is a magnificent addition to any landscape where it has room to spread its branches.
