Madagascan marigold (Tagetes minuta) is a species of marigold native to South America but widely naturalized in various environments, including Madagascar. It is often referred to as Mexican marigold or black mint. Madagascan marigold is an annual plant characterized by its strong growth, reaching heights of up to 2 meters. Its leaves are finely divided and fern-like, and it bears small, yellow to orange-yellow flowers typically clustered in small groups.
The scent profile of Madagascan marigold is notably intense and pungent. The plant contains essential oils that release a powerful aroma, often described as sharp and herbaceous with a somewhat medicinal quality. Notes of citrus can be subtly detected, adding a slight freshness to its dominant spicy and musky undertones. This robust fragrance can be overpowering and is reputed for its ability to repel insects and pests. Essential oils from Madagascan marigold are sometimes used in perfumery for their unique and potent scent, especially in creating fragrances that require a bold, herbaceous element.
