This two-day event is inspired by this year's Serpentine Gallery Pavilion designed by Peter Zumthor and the garden inside, designed by Piet Oudolf. Around 50 figures working in horticulture, design, architecture and art will explore the significance of gardens in their respective fields. Participants include Adam Curtis, Marcus du Sautoy, Peter Saville and Dan Pearson.
