The traditional flower of Los Dias de los Muertos is the yellow marigold , which is spread on paths and used to decorate ofrendas and the cemetery. Its pungent scent is thought to help the spirits of the dead find their way home. Aromas are what attract and guide the spirits of the dead, so the pleasant odors of foods, copal incense, and marigolds help guide souls home and provide offerings.
