Ohio Buckeye is also known as “fetid” buckeye because everything about the tree smells like a skunk. All parts of the tree are also poisonous to most animals, although bees do not seem to have a problem with the Ohio buckeye. There is a variety in California that has toxic nectar, but this is not a concern in the Midwest. Buckeye leaves are composed of 5 leaflets extending from a central stem. Flowers are yellow and appear in upright clusters early in the spring. Nectar flows in April and May. There are no known problems with consuming honey made with Ohio buckeye nectar. This tree only produces a minor flow, so any buckeye nectar would be mixed in with several other types of nectar.
