Published to coincide with the bicentenary of the Royal Horticultural Society, Gardens Through Time tells the history of garden design through the story of the RHS; it celebrates two hundred years of gardening and looks at the people, the ideas and the inventions behind the passion. In their major BBC Two series, being broadcast this autumn, Jane Owen and Diarmuid Gavin follow in the footsteps of the gardeners, designers and botanists of the past to see how their work and ideas have influenced and shaped the designs of today.
