The RHS is the world's largest gardening charity but what it does and why is little understood and rarely celebrated. From defining new gardening trends at the Chelsea Flower Show, to ranking the best dahlias to grow at the Wisley trial grounds, to inspiring communities with Britain in Bloom, educating children to grow and eat their veg through the Campaign for School Gardening, the RHS works tirelessly to improve the gardener's lot. With the use of evocative archive images and contemporary photos by award-winning Jason Ingram, this beautiful book explores the past, present and future of this most influential organisation by listening to the voices of those working today. From the thousands of volunteers in the society's five unique gardens (Wisley in Surrey, Rosemoor in Devon, Hyde Hall in Essex, Harlow Carr in Yorkshire and new addition Bridgewater in Salford), to the one million visitors to its inspirational flower shows (including Chelsea, Hampton Court, Tatton Park, Cardiff, Wisley and Chatsworth); the society gives meaning to more than 475,000 members, millions of television viewers and visitors from around the world. The RHS is the best of gardening, and this book presents the best of the RHS. Behind the scenes, access all areas, this book will give lasting pleasure to anyone who enjoys their garden.
