Thai Sweet Basil, or Anise/Licorice Basil (Bai Horapa): This tropical variety of sweet basil provides the unusual basil flavor present in so many Thai dishes that it has come to be identified as “Thai basil” in America, even though the Vietnamese and Laotians also use lots of it in their cuisines. Its leaves are deep green, smaller and not as round as Western sweet basil. They grow on purplish stems, topped with pretty, reddish purple flower buds. Both leaves and edible flowers are sweetly perfumed with a mix of a distinctly basil scent and that of anise or licorice. Therefore, it is, therefore, sometimes referred to as “anise basil” or “licorice basil,” though it is not the same as the Western strain of these basils stocked by local plant nurseries.
