Marigold And Calendula Differences
French Marigold, African Marigold, Signet Marigold, Pot Marigold, Tagetes erecta, Tagetes patula, Tagetes tenuifolia, Calendula officinalis
People are often confused between Marigold and Calendula. Several reasons: they are both members of the daisy family, Asteraceae. They are both sun-loving plants with cheerful flowers in shades of yellow, orange, or white from summer to fall. Some of this confusion is also somewhat reinforced by the fact that Calendula is commonly known as Pot Marigold, English Marigold, or Scotch Marigold. However, it is not a true Marigold.
But while Marigolds share many similarities to Calendula, they are two very different plants and should not be substituted for each other.
