Its yellow/ orange flowers are compositae, solitary, up to 7cm in diameter surrounded by two rows of hairy bracts. Its fruit is a thorny curved achene.
Calendula officinalis, commonly known as Pot marigold, Common Marigold, Garden Marigold or English Marigold, is 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 naturalized further north in Europe. This plant has a long history of culinary and medicinal uses and has been use as a dye.
The etymological root of the binomial name Calendula is derived from the Latin calendae ’the first day of the month’, possibly alluding to the flowering of the plant throughout the year. Officinalis is derived from the Latin meaning ‘of the apothecaries’.
