  • Grows up to 24-30 in. tall (60-75 cm) and 12 in. wide (30 cm). Pot Marigold will self-seed if not deadheaded, without becoming invasive.
  • Performs best in full sun in a light, poor to moderately fertile, well-drained soil. Some afternoon shade is tolerated in hot summer areas. Because Calendula are cool-season flowers, they often sulk when summer sets in, especially in hot-weather areas.
  • Water regularly until the plants are established. Mature plants thrive on only occasional watering. Drought tolerant once established.
  • Pot Marigold is a great choice for beds and borders, edgings, as a ground cover, or in mass plantings. It is also suitable for cut flower gardens and containers and looks great in the cottage garden.
  • Calendula is a wonderful companion plant in the garden. Butterflies, bees, and other pollinators and beneficial insects are drawn to the flowers, making them a useful addition to the vegetable garden.
  • In addition, Calendula is a trap crop, trapping pests such as aphids, whiteflies, and thrips by exuding a sticky sap (resin) that they find more appealing and delicious than nearby vegetable crops.
  • Calendula flowers can be harvested to make brightly colored bouquets. They can be used as a medicinal herb as they possess wound-healing and local anti-inflammatory properties.
  • The leaves and petals of this plant are edible. The leaves are often added to salads and the fresh petals can be used as a garnish or seasoning.
  • Seeds can be sown directly in the garden just before the last frost date, but for earlier bloom start seeds indoors about 6-8 weeks before the last frost. Successive sowings will provide fresh, blooming plants throughout the season.
  • If flowering performance dwindles in midsummer, cut back severely.
  • Young plants may be pinched back to encourage compact bushy growth. Deadhead spent flowers to promote additional bloom. Cut back to ground level after flowering.
  • Few insects or diseases bother Pot Marigolds. Keep an eye out for aphids, powdery mildew, and occasional cucumber mosaic virus. Deer and rabbits tend to avoid Calendula.
  • Calendula officinalis is native to Southern Europe.
