Calendula officinalis (also known as marigold, ruddles, common marigold or Scotch marigold) is a plant in the genus Calendula of the family Asteraceae. 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 further north in Europe (north to southern England) and elsewhere in warm temperate regions of the world.
Calendula officinalis is a short-lived aromatic herbaceous perennial and can be grown easily in sunny locations in most kinds of soils. Calendulas are considered by many gardening experts as among the easiest and most versatile flowers to grow in a garden, especially because they tolerate most soils.
