Tagetes foetidissima is a Mesoamerican species of marigolds in the sunflower family. It is widespread across much of Mexico and Central America from Tamaulipas to Costa Rica.[1] Common name is "flor de muerto," Spanish for "death flower."[2][3][4]

Tagetes foetidissima is a branching annual herb sometimes as much as 100 cm (40 inches) tall. Leaves are up to 9 cm (3.6 inches) long, divided into 11-29 toothed leaflets. One plant produces many small flower heads in a flat-topped array, each head contains 5 small, pale yellow ray florets surrounding about 7 greenish-yellow disc florets. The head is cylindrical, with purple bracts along the outside.[2]

The plant grows in disturbed areas and has been reported as a weed in cultivated maize fields. It is aromatic but with an odor that most humans find disagreeable.[5]
