The Beth Chatto Gardens began in 1960 when the site was an overgrown wasteland between two farms. Faced with all kinds of difficult conditions Beth and Andrew Chatto set out to find homes for many of the plants they wished to grow. With dry and damp soil in both sun and shade, they were able put into practice the underlying principles of what is now referred to as "Ecological gardening".
There are three gardens - Mediterranean, Water, and Woodland.
