Introduced in 1798 from its native Mexico, this edible flower was once known as Sweet-Scented Chili Marigold, but today is more commonly known as Mexican Tarragon. Lucida means shining, referring to the shiny aromatic leaves that offer a rush of sweet anise scent when bruised. A winner in our trials, it looked perfect all summer and fall, not bothered by weather extremes or insects, and becoming adorned in summer with clusters of petite yellow blooms.
