Greenhouse Three

Glass greenhouse filled with exotic dangerous magical plants including Mandrakes and Venomous Tentacula, damp earth compost pots.

Greenhouse Three, a steamy glasshouse at Hogwarts teeming with perilous magical flora like Mandrakes and Venomous Tentacula, debuts in the series as the nerve center for Herbology's most hazardous lessons. In Chamber of Secrets, it becomes the stage for the dramatic repotting of shrieking Mandrakes, whose cries are key to curing petrification victims from the basilisk's gaze. Though it fades from prominence in later books, its damp, compost-filled confines embody the wild, unpredictable magic of Professor Sprout's domain throughout the saga.
