Horse Chestnut (Aesculus hippocastanum)
The Horse Chestnut, scientifically known as Aesculus hippocastanum, is a deciduous broadleaf tree admired for its aesthetic qualities and historical uses. The common name "horse-chestnut" is often unhyphenated and thought to originate from the mistaken belief that the tree was a type of chestnut.
