Prof Kathy Willis, Director of Science at the Royal Botanic Garden, Kew, with the omnibus edition of her history of our changing relationship with plants during the 19th century.

She examines the race to tame and culture the prized Amazonian water lily which played out in glare of the nations' new greenhouses; the smuggling of rubber seeds out of Brazil to establish a rubber industry in the British colonies; how a growing passion for orchids opened a new episode in cultivating exotic plants for all; the threat posed by the rise of invasive species; and how a new precision in understanding the behaviour of hybrids led to the birth of modern genetics at the close of the 19th century.
