Pot marigold

Pot marigold (Calendula officinalis) is a plant in the genus Calendula (pot marigolds), in the family Asteraceae. It is probably native to southern Europe though its long history of cultivation makes its precise origin unknown, and 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.
