Herbology is a required class taught at Hogwarts, and deals with the study of magical plants and fungi. It is taught by Professor Sprout while Harry Potter is attending Hogwarts, and sometime after the Battle of Hogwarts but before the year 2017, Neville Longbottom takes over the subject. The classes are taught outside, within the greenhouses just outside the school's walls. There are two known textbooks to be required for the course: One Thousand Magical Herbs and Fungi and Flesh-Eating Trees of the World.
