context_section_description: The flag of the Brussels-Capital Region depicts the Iris pseudacorus (yellow iris), which is native to the Brussels area, against a blue backdrop.
  The valley of the river Senne has been housing Brussels for more than 1,000 years. With time, the lower town has progressively spread through the marshy bottoms. In the Dukes of Brabant's times, the marshy plains covered with golden irises encircled the town walls.
  According to a legend, this simple plant gave a great strategic victory to the Duke's soldiers. Those knew that iris can grow immersed only in a few centimeters of water. They broke into a gallop through the flooded plains but carefully let their horses stamping iris hills. Their opponents, less knowledgeable in botanics and encouraged by the apparently careless gallop of the Duke's soldiers, got definitively bogged into the marshes.
  Iris pseudacorus is the scientific name of the golden iris, the symbol of the region of Brussels-Capital, which is widely used (tramways, subway, taxis etc...) but ill-known.
  The choice of this marsh iris as the symbol of Brussels did not occur for the creation of the region of Brussels-Capital (18 June 1989), as often believed.
  In 1924, R. Cornette wrote that "this flower was chosen because it grows in the marshes, recalling that the capital was funded on the marshy banks of the Senne river and its tributaries" (Maalbeek, Roodkloosterbeek, Geleytsbeek, Kerkebeek, Leybeek, Woluwe...).
  Nowadays, in spite of the ultra-rapid urbanisation, the iris can still be found in its naturel habit in the vale of Vuylbeek, in the forest of Soignes.
