Native to southern Europe, it has been cultivated across the world for its ornamental beauty and medicinal value. With its vivid yellow-to-orange blossoms, calendula brings warmth and brightness to any garden throughout the growing season.
The term “calendula” originates from the Latin word calendae, which translates to “little calendar,” a nod to the flower’s tendency to bloom with the beginning of each new month.
