Ever wonder where Ohio’s nickname came from? Ohio is commonly referred to as “The Buckeye State” due to the prevalence of the Ohio Buckeye, named Ohio’s official state tree in the 1950s. According to USDA’s Natural Resources Conservation Service (NRCS), the name refers to the tree’s nuts and their resemblance to the eye of a deer. But don’t eat these nuts! NRCS warns that all parts of the Ohio Buckeye are toxic to humans and livestock. Luckily there are many other things we can eat that come out of this great state.
