Wild Calendula (Calendula arvensis) is thought to be the original parent plant of domesticated Calendula (Calendula officinalis). This small, bushy plant produces a profuse number of small, yellow flowers that beneficial insects adore. Thought to be medicinally less-potent than C. officinalis, though no less potent in beauty! Easy to grow and self-seeding. Hardy re-seeding annual/tender perennial.
