A seasonal floriculture project combining the sale of flowers in fresh and dried bouquets, the sale of seeds and events will be created on one of the wastelands of the famous Murs à Pêches in Montreuil. The Murs à fleurs de Petite Couronne project also plans to establish partnerships with local actors, among others with a view to working on horticulture (Greta, Lycée Horticole de Montreuil), to rehabilitate the peach walls or to implement a soil phytoremediation area.
