Description
Ohio buckeye (Aesculus glabra). Close up of the nut fruit of an Ohio buckeye tree (Aesculus glabra) picked up and laid on a wooden bench. The mature "chestnut" fruits have smooth cases, unlike the horse chestnut trees that are more common in the UK, and the outer skin on older nuts quickly turns to a dark purple colour. These "chestnuts" are poisonous to humans.
