Mexican Mint Marigold
This herb is covered with masses of tiny yellow flowers late into the fall. It prefers full sun and works well in a perennial border or herb garden. Use it as a substitute for French tarragon, which does not like hot, humid Southern summers. Enjoy its licorice scent in the garden and in your kitchen creations. Use it as a perennial in the Middle, Lower, and Coastal South; treat it as an annual in the Upper South.
