Since 1992, the International Garden Festival in Chaumont-sur-Loire has been providing a unique international platform for landscape design. Every year, professionals, students and garden aficionados are invited to present a project around a specific theme. Around twenty gardens are selected by a jury among over 300 proposals from all over the world. A “free green hand” are also given to artists, architects or celebrities to design a garden. This year, the theme for the 20th edition of the festival will be "Gardens of the Future or the Art of Happy Biodiversity", with a jury presided by the botanist Jean-Marie Pelt, founder of the European Institute of Ecology (1971).
