The Spanish word "flores" means "flowers". In the tradition of Día de Muertos, marigold petals are an important symbol. They are believed to guide the spirits of the departed to their families' ofrendas (altars).
Note that the Spanish word "altares" means "altars". Ofrendas are altars that are set up to honor the spirits of the departed during Día de Muertos. They are typically decorated with marigold petals, candles, food, drink, and personal items that belonged to the deceased.
