Derivation of the botanical name: Calendula,from the Latin kalendae, "first day of the month" in the Roman calendar, since they can be found in flower at the beginning of most months of the year. arvensis, arvum, field, cultivated land, plowed land; ensis, country or place of origin or habitat; of cultivated fields. Marigold, refers to its link with the Virgin Mary. The Hebrew name: צפרני-החתול, tsiporne-chatul, cat’s claws, for the fruit looks like a cat’s paw with drawn claws. The standard author abbreviation L. is used to indicate Carl Linnaeus (1707 – 1778), a Swedish botanist, physician, and zoologist, the father of modern taxonomy.
