What is Calendula officinalis?
Calendula officinalis is a cheerful annual herb that happily thrives in the sunny spots of south-central Europe and North Africa, bringing joy to gardens all around the world! With its bright yellow and orange blooms, this delightful plant opens its petals in the morning, basking in the sunlight, and gently closes them at night. It’s no wonder that the herbalist Nicholas Culpeper lovingly called it “an herb of the sun” back in 1653—these flowers really seem to capture the warmth and light of sunny days!
Commonly known as marigold, calendula got its name as a nod to the Virgin Mary during the Middle Ages (McIntyre, 1996). Just a little fun fact: while people often mix it up with the marigold from the genus Tagetes, calendula belongs to a different botanical family.
Beyond its charming appearance, calendula has a rich history of practical uses. People in Croatia often create a macerate from its lovely golden blooms by soaking them in quality oil for several weeks. This simple but effective process results in a beautifully infused oil known for its wonderful healing properties—it’s great for soothing and nurturing the skin. Calendula truly embodies the essence of sunshine with its long-standing reputation as a natural remedy, combining both its medicinal benefits and its radiant personality!
