Marigolds arenative to Central and Southern Mexico and several other Latin American countries.The Nahua people called them "cempōhualxōchitl".Some marigold species have become naturalized and even invasive in other parts of the world.

In pre-Hispanic Mexico, marigolds, known as "cempasúchil" in Nahuatl, were deeply revered and considered the flower of the dead. Their vibrant orange and yellow hues were believed to guide spirits back to the world of the living. During the Day of the Dead, or "Día de los Muertos," these flowers play a crucial role in altars and offerings, known as "ofrendas," which are set up to honor and remember deceased loved ones. The marigolds' strong scent and bright colors are thought to attract the souls of the departed, helping them find their way back for the annual reunion with their families. This tradition embodies a blend of indigenous beliefs and Catholic influences, celebrating life and death in a joyous, respectful manner.
