Calendula (Pot Marigold) Calendula officinalis, Asteraceae. Calendula is one of the most familiar and beloved herbs, earning our affection with its cheerful golden flowers. The “petals” are edible and the whole flower is an important medicinal herb in treating skin conditions. Calendula is found in topical ointments, salves and creams. This flower holds an interesting claim to fame—it is the herb most likely to be found in diaper rash ointments and creams. I plant calendula close to my front porch so I can enjoy the blooms, and watch the hum of pollinator activity all summer long. Calendula prefers full sun and average garden soil. It is easily grown from seed—direct sow or start early in pots; the seedlings are somewhat cold tolerant. Calendula does well as a container plant, hence the common name “pot marigold.” Plant 10-14’’ apart; grows to 18’’ tall. Calendula’s sticky flowers must be picked every two to three days to ensure a longer flowering season. Calendula will usually self-sow unless you mulch heavily. It is typically grown as an annual, but can be cultivated as a short-lived perennial in warmer climes (Zone 8-10).
