Completed in 1898, the greenhouse allowed John Morris to grow exotic plants under glass and then transplant them onto the grounds. Very little remains of the original structures in the area. The headhouse was built in the early 1940s and current greenhouses were rebuilt in 1998. The only remaining structure from the Morrises' time is the one cold frame closest to the fernery.
