Tagetes

Common name: Marigold

Tagetes is a genus of annual and perennial herbs in the daisy family, Asteraceae, native to the Americas, especially Mexico. Marigolds produce bright yellow, orange, and red composite flowers over a long season and are among the most popular bedding plants in the world. They are also grown as companion plants, since their roots and scent can deter some pests.
