Sweet Mace Tagetes lucida

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 are native to Central and South America and have been introduced throughout the world. Tagetes lucida, or Mexican Tarragon, is native to the hill sides and woodlands in Mexico and South America where it is a perennial. In zones colder than 8 it is grown as an annual. It has cheerful yellow composite flowers that appear in the 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 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. The juice, sap, or thorns of these plants may cause a painful skin rash or irritation. Wash the affected area of skin with soap and water as soon as possible after contact.
