The Sprout Arboretum is a four-story Herbology center on the campus of Hogwarts School of Witchcraft and Wizardry. The building houses a multitude of eco-systems, supporting tropical plants, desert plants, mountainous plants, and wintry tundra plants. Several atmospheric charms appear to maintain each eco-system's necessary environment.
The outer glass of the arboretum is enchanted to appear green. A room on the first floor serves as a classroom, and a room on the fourth floor serves as the Herbology professor's office. The Arboretum is named after former professor of Herbology Pomona Sprout.
