Calendula (Calendula officinalis)

Calendula, also known as pot marigold, is a flowering plant in the Asteraceae family, with 15 to 20 species. Originating from the Mediterranean region, calendulas have been used for medicinal purposes, culinary uses, and aesthetic appeal. The plant's name comes from the Latin word "calendae," meaning "first day of the month," as the flower tends to bloom at the beginning of each month. Calendulas have been used for various purposes, including treating skin conditions, wounds, and infections, adding color and flavor to food and drinks, making skin creams, ointments, and dyes for fabrics and hair, and being used in religious ceremonies, particularly in Christian contexts. Calendulas are easy to grow and can be considered a hardy annual or perennial in warmer climates. Key factors for cultivating calendulas include well-drained soil, sunlight, watering, temperature, spacing, fertilization, deadheading, propagation, pest and disease resistance, companion planting, and flowering. They are also known to deter pests and improve garden health.
