What's on Festival Programme Fiona Davison – The Hidden Horticulturists Fiona Davison studied history at the University of Oxford and joined the Royal Horticultural Society in 2012 as its Head of Libraries and Exhibitions. The Hidden Horticulturalists traces the stories of a selection of forgotten working class 19th Century gardeners. The trail took Davison from Chiswick to Bolivia and uncovered tales of fraud, scandal and madness - and, of course, a large number of fabulous plants and gardens. The book is a celebration of the unsung heroes of horticulture whose achievements reflect a golden moment in British gardening, and continue to influence how we garden today.
