From May to September 2022, you can discover a floral clock specially designed for the Bernese climate in the BOGA, Bern, Switzerland. Test whether you can tell the time and discover the mechanisms responsible for these floral movements!
How do flowers know the time? How are the movements of the petals triggered? How and why do many species perform these complex floral movements? These questions have been studied by many scientists from different fields of research: ecology, physiology or chronobiology. However, until now, there is surprisingly little information on the flower opening period of each species and what triggers the floral movements of each species.
