Buckeyes and horsechestnuts are members of the genus Aesculus. The true chestnuts are members of a different genus - Castanea. Members of the genus Aesculus have palmate leaves – meaning they have 5-7 leaflets that fan out like fingers on your palm. They have showy flowers in spring, which mature to large dark brown capsules in late summer or early fall. While the hard, shiny buckeye fruits are considered good luck when carried in your pocket, they should not be eaten since they are poisonous to people.
