Description: French Marigold ink drawing depicting the beautiful garden flower Tagetes patula. It is a close relative of the Aztec or African Marigold. In addition to its beauty, people use it as a yellow dye and as a medicinal plant due to its essential oil - it has antiseptic, anti-inflammatory, anti-parasitic action and even more. Marigold is even used in perfumery and for seasoning your salad. Here where I live I can see it in most gardens and it’s bright and very, very pretty.
