Native to Argentina and Chile, Lemon Verbena is a woody shrub that produces shiny, green leaves that have a strong lemon aroma and flavor. Plants are evergreen in tropical/warm winter locations, but deciduous in areas where freezing temperatures occur. Lemon verbena has been a popular garden plant in warm southern and western parts of the U.S. for many years. Leaves and flowers are used for culinary purposes (teas, desserts, fruit salads and jams) for perfumes and cosmetics, for potpourris and as herbal medicines (colds, fevers, dyspepsia and diarrhea). Harvest leaves at the time of flowering to get the strongest scent. Spanish explorers brought this plant to Spain in the 17th century, at which point it was named after Princess Louisa of Parma.
