To celebrate the mole, the Talpa europea, this small, harmless mammal that is so useful to our soil and yet unfairly castigated and fought off, here is a sundial in a wildflower setting that highlights the main points of the animal’s underground work. Observers will indeed note that the small mounds of earth, or molehills, appear three times a day around 7am, 12am and 5pm — even though Pully’s moles may have their local habits and might show themselves at slightly different times. Thanks to their digging, short-cycle crops (yearly wild flowers which have now disappeared from agricultural areas) emerge. The moles preserve the threatened diversity of farmland. 

Throughout the summer (17/6-22/9), the Gilles Clément: Toujours la vie invente exhibition will feature a panoramic vision of the world-renowned gardener’s works and thoughts at the Orangerie du SPADOM. On 27 August, the Cantonal Botanical Museum and Gardens, Archizoom | EPFL, the EPFL Sustainable Campus and Lausanne Jardins 2019 will organise a day-long event with and about Gilles Clément.
