Calendula (Calendula officinalis)

This flower is a self seeding annual. It originates from Europe, but is commonly used as food and medicine. This bushy plant produces daisy like flowers that are often red, orange, or yellow. Once the plant blooms, it will bloom continuously until frost. Once the flowers die back, the seeds can be collected for sowing later or it can be sown immediately depending on when the seeds are gathered. This plant will not always overwinter in Southern Ohio due to our cold weather temperatures, but if the seeds get dropped into the soil, it may regrow next year. The leaves and petals of this plant are edible. The leaves are somewhat bitter and are often enjoyed in salads, the petals have been used as a seasoning, coloring, or garnish. This flower has been used historically for dying food and clothes, medicine, and cosmetics.

Planting/Harvesting Notes

  • Plant in an area that receives 6-8 hours of full sun each day. If planted in an area with 3-6 hours of sunlight, the plant will grow but will not bloom as aggressively.
  • Plants perform better with minimal fertilization.
  • Water at least weekly.
  • Space plants 12-18 inches apart.

Seed saving notes

Allow flower to die on the stem. Once the flower is dead, large curved brown seeds should be found on the head. You can bag these dying flowers with organza bags to make it easier to gather the seeds before they fall of the flower stalk. Store seeds in a labeled paper envelope.
