"We’ll be repotting Mandrakes today. Now, who can tell me the properties of the Mandrake?"
—Professor Sprout teaching second years about Mandrakes in Greenhouse Three[src]

Greenhouse Three was where Herbology classes were taught to every student, except first-years, because it was used to house several spices of magical plants that were deemed too dangerous for them to handle.[1] The room had more dangerous species, such as the Venomous Tentacula, as it was for the advanced students.[1] First year students took the class in Greenhouse One, which had no dangerous material.[2]
