Sweet Basil Types
While Ocimum basilicum is the botanical name, this herb is most commonly known as sweet basil in culinary and wellness circles. It is important to note that “sweet basil” typically refers to the Genovese cultivar, but several popular varieties actually fall under the Ocimum basilicum species:
Genovese Basil (Classic Sweet Basil)

- Best For: Pesto, Caprese salads, and Italian sauces
- Key Difference: Contains the highest eugenol content and is the most widely available variety in Western markets
Thai Sweet Basil
