Behind the scenes at the Botanical Gardens all kinds of surprising things have been going on. As the British Empire painted the atlas red, explorers, adventurers and scientists brought the most interesting specimens and information back to London.

From the discovery of Botany Bay to the horrors of the potato famine, from orchid hunters to quinine smugglers, from Darwin's experiments to the unexpected knowledge unlocked by the 1987 hurricane, understanding how plants work has changed our history and could safeguard our future.

In the style of A History of the World in 100 Objects, each chapter tells a separate story, but, gathered together, a great picture unfolds, of our most remarkable science, botany.

Plants: From Roots to Riches is a beautifully designed book, packed with 200 images in both colour and black and white from Kew's amazing archives, some never reproduced before. Kathy Willis and Carolyn Fry, the acclaimed popular-science writer, have also added all kinds of fascinating extra history, heroes and villains, memorable stories and interviews. Their book takes us on an exciting rollercoaster ride through our past and future and shows us how much plants really do matter.
