Identifying the Buckeye Tree: Nuts, Leaves, and Key Characteristics

A homeowner's granddaughter found a nut tree with leaves resembling beech or chestnut and fruits that look like apricots from the outside. As they ripen, the husks split open to reveal three off-white, clove-like sections with no scent. This description matches the buckeye (Aesculus species), specifically the Ohio buckeye (Aesculus glabra).

Distinguishing Features

• Leaves: Palmately compound, usually with five leaflets, similar to chestnut but with finer serrations.
• Fruit: A leathery, globular husk that splits into sections when mature, each containing one or two shiny, dark brown nuts with a pale hilum—resembling a deer's eye.
• Odor: Crushed leaves, twigs, bark, and flowers emit a disagreeable, fetid smell, giving rise to the name "fetid buckeye."
• Range: Native to the Midwest and Great Plains; the state tree of Ohio.

Ecological and Cultural Notes

Buckeyes are often planted as ornamental shade trees. The nuts are toxic to humans and livestock if eaten raw but were historically used by Native Americans after leaching. The tree's early spring flowers attract pollinators, and its dense canopy provides good shade.
