Calendula, marigold, is a genus of about 12-20 species of annual or perennial herbaceous plants in the daisy family Asteraceae, native to an area from Macaronesia east through the Mediterranean to Iran. Calendula should not be confused with other plants that are also known as marigolds, such as corn marigold, desert marigold, marsh marigold, or plants of the genus Tagetes. The name "calendula" is a modern Latin diminutive of calendae, meaning "little calendar", "little clock" or possibly "little weather-glass". The common name "marigold" possibly refers to the Virgin Mary. Claims that its old Saxon or Anglo-Saxon name is 'ymbglidegold' are unsubstantiated, as is the claim that this means 'it turns with the sun'.
