Professor Sprout’s Greenhouse – Step into the world of herbology

Professor Sprout’s Greenhouse brings Herbology class to life with earthy textures, enchanted plants, and the wizarding world’s noisiest flora. Located within the backlot, this fan-favourite set allows you to step inside the lush, vine-filled glasshouse and even try your hand at pulling a shrieking Mandrake from its pot.

Where is it located?

The greenhouse is situated in the Backlot of the Warner Bros. Studio Tour London, located outdoors between the interior soundstages and the exterior sets like Privet Drive and the Hogwarts Bridge.

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.

Architectural highlights of Professor Sprout’s Greenhouse

Historical and cultural significance

The greenhouse made its iconic debut in Harry Potter and the Chamber of Secrets (2002). It represents the "living" side of Hogwarts, shifting the tone from cold stone corridors to a vibrant, albeit dangerous, natural environment. Culturally, it remains one of the most beloved sets because it highlights the "practical" side of magic, showing that even wizards have to get their hands dirty to master the craft of Herbology.

​Get directions

  • The Mandrakes can be loud! If you have sensory sensitivities, you may want to view the interactive display from the greenhouse entrance.
  • 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.

​Plan your visit

  • Photography is highly encouraged, but be mindful of the bright "simulated sunlight" lighting, which can cause glare on the glass panels.
