What Is the Scientific Name for Marigolds?

The scientific name for marigolds is Tagetes patula. Marigolds are an annual, herb plant that develops maroon, orange, red, mixed and cream-colored flowers and belongs to the Compositae family of plants. The plant is believed to have originated in New Mexico, Argentina and in other parts of South America and is divided into four different species, which are French marigolds, Single marigolds, African marigolds and triploids.

Marigolds grow best in areas with moist, warm soil and where there is plenty of sun. They are at risk from diseases and insects such as wilt, aster yellows, spittle bugs and spider mites and may not grow and survive if exposed to frost. Marigolds are also likely to experience delayed flower growth if they do not receive enough sunlight.
