Sisymbrium irio, London rocket, is a flowering plant in the cabbage family which is native to the Middle East, north Africa and southern Europe, and which has spread widely around the world as an invasive plant of dry, disturbed land in towns, deserts and farmland. It has traditionally been used as a medicinal herb for a variety of ailments. Its English common name originated when it flourished after the Great Fire of London in 1666, although it is not native to Britain and it does not tend to persist there.
