From the misty subtropical canopy to sun-baked Mediterranean terraces, each zone is a living biome — a portal to another continent.
Our curators highlight six extraordinary plants — living relics of expeditions past and conservation milestones.
Returning from expeditions in South America, Victorian botanist Sir Arthur Pendelton constructed our iconic octagonal glasshouse, filling it with orchids and bromeliads from the cloud forests of Ecuador.
The gardening team noticed the mild Gulf Stream weather protected clifftop plants from frost. They began planting giant Australian tree ferns and Chilean gunnera directly into the open Cornish soil.
Post-war restoration brought Mediterranean species to the south-facing slopes — olive trees, bougainvillea, and lavender borders that transformed the clifftop into a Riviera-like panorama.
The Pendelton Estate transitioned to a charitable trust, securing long-term protection of the gardens and opening the gates to international researchers and the public year-round.
3,000+ species, climate research partnerships with the University of Exeter, and a new tropical butterfly house opening Spring 2025. The garden has never been more alive.
Tickets include full access to the 12-acre outdoor cliff gardens, all three historic glasshouses, and the clifftop tea room. Under 5s enter free.
The gardens are located 2 miles west of St Ives harbour on the clifftop road. Free car parking is available for all ticket holders.
