When we think of our most famous prehistoric site, Stonehenge, we don’t automatically think of flowers. But in 1842, the site played host to a huge dahlia exhibition, attended by around 10,000 people.

Joining us to reveal the story of this event and how it is being recreated over four days this autumn are English Heritage landscape advisor and historian Louise Crawley and archivist for the National Dahlia Society David Brown.
