Buckeye vs. Chestnut — What's the Difference?

Buckeye and Chestnut are terms that often refer to trees and their respective seeds or nuts. Buckeyes are primarily associated with trees or shrubs in the genus Aesculus. These trees produce seeds that are inedible and can even be toxic. They are characterized by their shiny appearance and a distinct "eye" marking, which gives them their name. Chestnuts, on the other hand, are from trees belonging to the genus Castanea. These trees yield nuts that are edible and are often used in culinary dishes around the world.

While both Buckeye and Chestnut trees bear similar-looking seeds/nuts, they have clear differences. Buckeye seeds are larger and feature a prominent, glossy brown seed with a paler "eye" spot. Chestnuts, in contrast, are encased in a spiky burr and, when removed, reveal a nut that's both edible and tasty.

It's important to note that while Chestnut trees produce nuts cherished in various cuisines, consuming a Buckeye seed can be harmful. Mistaking a Buckeye for a Chestnut and eating it may result in sickness. Therefore, it's vital to distinguish between the two, especially when foraging.

Culturally, the term "Buckeye" has significance in the U.S., particularly in Ohio, which is known as the "Buckeye State." The tree is symbolic to Ohioans. Chestnut trees, meanwhile, have had both cultural and economic importance in various regions, especially in parts of Europe and Asia, where the nuts are celebrated and incorporated into numerous dishes.
