Calendula officinalis, Mary's gold, common marigold, the pot marigold, Scotch marigold, or ruddles, is a flowering plant in the daisy family, Asteraceae. It is probably native to southern Europe, but its long history of cultivation makes its precise origin unknown, and it is widely naturalised. The florets are edible and the plant has historically been used as medicine.
Still missing: plant type, natural habitat, height / growth form, flowering period, growth & dormancy period.
