Ventnor Botanic Garden lies in the remarkable microclimate at the heart of the famous ‘Undercliff.’ This unique garden is protected from the cold northerly winds by chalk downs. Indeed, it holds the warmth from its southerly aspect so well that, combined with the moderating influence of the sea, frost is rarely known. When frost does occur it is usually of short duration and not great severity.

With an average rainfall of 28 inches its climate is more akin to the Mediterranean. This enables a wide variety of plants considered too tender for much of mainland Britain to be grown.

The Garden is unrivalled for its collections of subtropical plants grown unprotected out of doors.

Many of our plants are shown in representations of geographical regions, growing in association with each other as in the wild. We aim to present an immersive experience where the visitor is transported to landscapes from around the world. There’s an impressive collection of succulents and cacti including huge spiky agaves and flowering aloes. Sun-loving herbs, giant echiums, vibrant tender bedding plants and mature palm trees thrive here, as do many colourful South African treasures, Australian eucalyptus, bottlebrushes, tree ferns, and much more.
