  • Botanical Name: Calendula officinalis
  • Other Names: Bullseye, garden marigold, genda, gold-bloom, holligold, marigold, pot marigold, marybud, zergul
  • Etymology: The name “calendula” comes from the plant’s tendency to bloom along with the calendar, typically flowering at the same time in the moon’s cycle. The name “pot marigold” comes from calendula’s use in German stews.il_570xN.266567222
  • Appearance: Calendula flowers range from yellow to orange. The blooms resemble highly-colored daisies. The stems grow from 30-60 cm (12″-24″). The flowers open in the morning and close at night.
  • Cultivation: Native to the Mediterranean, calendula grows in its natural habitat nearly year-round. An annual, calendula seeds can be sown directly in the garden in April or even in the fall in warmer climates. Although calendula prefers sunshine, rich soil, and occasional watering, it still grows well when neglected. Don’t be afraid to pick the flowers; the more you take, the more calendula gives. Flowers are ready to pick when they are sticky with anti-fungal resin.
