The French marigold (tagetes patula) is fair a bit smaller than the normal marigold and belongs to the family of the daisies.It is native to Mexico and Guatemala.They grow in yellow as you see,as well in red,orange,gold and mahogany color.I found them just across the road from where my parents in law live.
French marigold is a popular flower for the garden,as well for the vegetable garden.It keeps some bugs and harmful insects away.
The dried leaves from the flowers are used by many cultures in the process of infusion as a medical treatment.
The essential oil is used in perfumery and you can use it as a pesticide against bedbugs.
