Pot Marigold at Wylam, Northumberland
Calendula officinalis, the pot marigold, common marigold, ruddles or Scotch marigold, is a flowering plant in the daisy familyAsteraceae. It is probably native to southern Europe, though its long history of cultivation makes its precise origin unknown, and it may possibly be of garden origin. It is also widely naturalised farther north in Europe (as far as southern England) and elsewhere in warm temperate regions of the world.
