About Calendula arvensis L.
Calendula arvensis is a species of flowering plant in the daisy family, commonly called field marigold. It is native to central and southern Europe, North Africa, and the Middle East, and is an introduced species in regions across the rest of the world. This species is an annual or biennial herb that grows 10 to 50 cm (3.9 to 19.7 in) tall. Its lance-shaped leaves grow on petioles that attach to a slender, hairy stem. The plant's inflorescence is a single flower head that reaches up to four centimeters wide; it has bright yellow to yellow-orange ray florets surrounding a center of yellow disc florets. Its fruit is an achene that can take one of three shapes, including a ring shape, and each different shape supports a different method of seed dispersal.
