Created in 1922 by Jean Massart (1865 - 1925), professor of botany at ULB, the Jean Massart Experimental Garden covers an area of 5 hectares. It has an extremely rich variety of flowers (almost 2000 species of plants are grown there). It enables the public to discover various thematic collections (medicinal plants, evolutionary garden, arboretum, cultivated plants, orchard) and a humid zone (ponds, marshes), a small natural reserve which is characterised by the presence of wild plants typical of this environment and exclusive to the Brussels region.
