The Chelsea Physic Garden was founded in 1673, as the Apothecaries’ Garden, with the purpose of training apprentices in identifying plants. The collection concentrates on medicinal plants and those of ethnobotanical interest, as well as rare and endangered species. Situated in the heart of London, Chelsea Physic Garden has a unique living collection of around 5,000 different edible, useful, medicinal and historical plants. Celebrating the beauty and importance of plants, this ‘hidden gem’ is also a peaceful green oasis in which to enjoy a relaxing stroll. The Garden’s warm microclimate means that many tender plants can flourish including a number of rare and endangered species. It has the largest outdoor fruiting olive tree in Britain and the world’s most northerly outdoor grapefruit tree. From pomegranates to gingkos, mulberries to eucalyptus, there are over 100 different types of tree in the Garden, many of which are rare in Britain. The glasshouses hold a collection of tropical and sub-tropical species, complemented by a Victorian Cool Fernery.
