Tagetes, or Marigolds, is a genus in the sunflower or aster family that includes 49 species of flowering, herbaceous plants with a shrubby form that is native to Central and South America and has been introduced throughout the world. Tagetes lucida, or Mexican Tarragon, is native to the hillsides and woodlands in Mexico and South America, where it is a perennial. In zones colder than 8, it is grown annually. It has cheerful yellow composite flowers in late spring and early fall.
Plant it in the full sun in light, well-drained soils. It tolerates most soil types, including clay; however, it cannot grow in full shade and is not particularly cold or hardy. Mexican Tarragon pairs well in vegetable gardens with tomatoes, or you can plant them in an herb garden, a border front, or along a pathway or patio. Propagate this plant by seed.
The plant is often used in tea, to color foods, and as a substitute for tarragon; however, it can be harmful if eaten in large amounts. These plants' juice, sap, or thorns may cause a painful skin rash or irritation. Wash the affected skin area with soap and water as soon as possible after contact.
