Established as the Apothecaries’ Garden in 1673, this is London’s oldest botanical garden. Its walls now shelter around 5,000 different medicinal, herbal, edible and otherwise useful plants. Hire the garden today and your money is ploughed back into its fertile soils. The options for private events include the Gallery; an outdoor awning; a marquee on the main Garden Lawn; or you can give yourselves the run of the Lower Lawn. Evening events, including candlelit canapé receptions, can be arranged.
