The calendula is an annual flower native to the northern Mediterranean countries. Its name refers to its tendency to bloom with the calendar, usually once a month or with every new moon. The term “marigold” refers to the Virgin Mary, and the flowers are used to honor her during Catholic events. The Egyptians considered calendula flowers to have rejuvenating properties. In the Hindu world, the flowers were used to adorn statues of gods in their temples, as well as a colorant in food, fabrics, and cosmetics, and of particular interest, in the 18th and 19th century calendula was used to color cheese.
