The RHS is inviting visitors to discover the remarkable story behind the iconic RHS Garden Wisley.

A new exhibition, Wisley: Then and Now, will run from Saturday (3 October) to Sunday, 31 January 2027.

Part of the RHS Growing Our Story theme, the exhibition explores how Wisley has transformed from a muddy Surrey landscape into one of the world's most celebrated gardens.

Through historic photographs, modern imagery and personal accounts, visitors can uncover the people, places and events that have shaped the garden over more than 100 years.

From the vision of George Fergusson Wilson, who first cultivated the Oakwood site in the late 19th century, to today's garden welcoming more than 1.25 million visitors annually, the exhibition reveals a legacy of experimentation, innovation and adaptation.

His passion for science, plants and innovation laid the foundations for what would later become RHS Garden Wisley.

Visitors will discover fascinating stories from Wisley's past, including lost buildings, storm damage, ambitious plans that never came to fruition and the challenges of moving mature trees before modern machinery.

Along the way, they will hear memories and insights from staff, students and long-standing members of the Wisley community.

RHS exhibitions and events manager, Fe Story, said: "The pioneering RHS gardens at Wisley have seen many changes over their long history, and that experimental spirit has been there from the very beginning.

“Across our varied and extensive collections, you can spot both constants and change, shaped by weather, people, ambition and scientific innovation, and by our ongoing response to visitor needs, a changing climate and evolving ways of gardening."

Wisley: Then and Now will be displayed in the Wisley Gallery, located within the iconic Old Laboratory, from 3 October 2026 to 31 January 2027.

Entry is included with normal garden admission, RHS Members go free.
