Garlic mustard or Hedge garlic (Alliaria petiolata) is a flowering plant in the Mustard family, Brassicaceae. It is native to Europe, western and central Asia, and northwestern Africa, from Morocco, Iberia and the British Isles, north to northern Scandinavia, and east to northern India and western China (Xinjiang). It often occurs along the margins of hedgerows, giving rise to the old British folk name of "Jack-by-the-hedge".
