Professor Sprout’s Greenhouse | Herbology Set from Harry Potter

The filmmaking magic behind Professor Sprout’s Greenhouse

Mandrake animatronics and puppetry: Each Mandrake is operated using rods and motors to control wiggling limbs and twisting roots. Facial details were sculpted in clay and then cast in flexible silicone for a lifelike plant-creature hybrid.
Weathering with real soil and moss: The props team used soil, preserved moss, and crushed leaves to add texture to every surface. Greenhouse benches, pots, and even tools were hand-aged to match the damp, earthy feel of a working glasshouse.
Prop layering for realism: Layers of real and fake plant matter were arranged by set decorators to make each shot feel spontaneous and full. Dead leaves, broken pots, and spills helped avoid any overly polished or artificial look.
Sound design with shrieking Mandrakes: Mandrake cries were designed using layered animal sounds and pitched-up vocals. They were added in post-production to sync with puppet movements, giving each scream a sharp, unearthly tone.
Clever lighting to simulate daylight: Though filmed indoors, the greenhouse glows with filtered light through aged glass panels. Hidden light sources mimic sunbeams and shadows, creating the illusion of outdoor light on plants and props.

Moments from the films recreated here

Herbology class with the Mandrakes

In Chamber of Secrets, students attend a Herbology lesson with Professor Sprout to repot Mandrakes. The greenhouse scene shows noisy, shrieking baby Mandrakes being pulled from soil, filmed on a specially built set filled with living and fabricated plants.

Greenhouse chaos after the basilisk attack

Also in Chamber of Secrets, the greenhouse becomes a place of recovery and tension after the basilisk petrifies several students. Professor Sprout uses Mandrake Restorative Draught, connecting earlier lessons to later scenes filmed inside the same lush, overgrown set space.

Background glimpses during Hogwarts transitions

While not always the focus, the greenhouse appears throughout the series in wide shots of Hogwarts grounds. Scenes in Prisoner of Azkaban and Goblet of Fire show it in the background, surrounded by mist, vines, and fluttering magical plant life.

What to know before entering the Professor Sprout’s Greenhouse?

The Mandrakes can be loud when pulled from the pot. Sensitive visitors may prefer watching from a little distance rather than participating.
Lighting is bright and warm to mimic sunlight, which can cause some glare on the glass panels and pots during photos.
You can try pulling a Mandrake, but they are firmly secured for safety. Ask staff if you're unsure where to interact.
The greenhouse can get warm on busy days. Take your time near the entrance where airflow is better and views are still great.
Most elements are viewable at multiple angles, and the space is accessible for wheelchairs. Staff can help guide to less crowded areas.
