Marigold, a genus within the family Asteraceae, encompasses a diverse group of flowering plants that have earned a place in gardens, cultural traditions, and herbal medicine around the world. T
he scientific name for marigold is Tagetes, and within this genus, there are both annual and perennial species. Known for their vibrant colors, distinct aroma, and various uses, marigolds have become a popular choice for both ornamental and practical purposes.

This aromatic quality has led to the use of marigold extracts in perfumery and cosmetics.
Beyond their ornamental value, marigolds hold cultural significance in many societies. In various traditions, marigolds are associated with celebrations and ceremonies.
In Mexican culture, for example, marigolds are a central element of the Dia de los Muertos (Day of the Dead) festivities, where they are used to create vibrant floral displays and altars honoring deceased loved ones.
Marigolds also find applications in herbal medicine. Certain species, particularly Tagetes erecta, have compounds that are believed to have anti-inflammatory and antioxidant properties.
Marigold extracts are sometimes used topically to promote wound healing and reduce skin inflammation.
