Thai Basil

Thai basil has a sweet, anise-like scent and hints of licorice, along with a slight spiciness that is lacking in traditional sweet basil, although Thai basil is simply another variety of sweet basil. Native to Southeast Asia, Thai basil has been specifically cultivated for its distinctive spicy flavor and its ability to remain stable under high or extended cooking temperatures, unlike traditional sweet basil. Thai basil plants are sturdy and compact and require well-drained soil.
