Origin of name
The name Calendula stems from the Latin kalendae, meaning first day of the month, presumably because pot marigolds are in bloom at the beginning of most months. The common name marigold most likely refers to the Virgin Mary, or its old Saxon name 'ymbglidegold', which means 'it turns with the sun'. Calendula means "small calendar" or "small almanac", yet remains ambiguous: does it refer to the weather or the passing time?
Marigold is one of the plants used in traditional pharmacopeia. It is known for its healing and anti-infection properties. Its effectiveness in treating skin problems (ulcers, burns and chilblains) is also recognized by official pharmacopoeia. In a garden, it is a good plant to place next to vegetables and roses as it is said to repel harmful insects and diseases.
From the Latin word "solsequia" (sunflower), its bright orange flower heads follow the sun and bloom during the "calends" of June, while providing beneficial skin care action... But, it is limited to external use. Robert Anton.
