Another type of basil that you'll find interesting is the Holy Basil. It's not your typical sweet basil to add to your pesto. But this one is something you can utilize for medicinal, spiritual, aesthetic, and some culinary purposes.
Native to the Indian subcontinent in Southeast Asia, the Holy Basil is another basil species popular in folk medicine as an herbal tea. This species belongs to the mint family (Lamiaceae) and can grow as an annual or short-lived perennial. Each shrub grows an average height of 3.3 feet (1 meter).
One way to identify Holy Basil is by looking at its leaves. The plant has greenish-purple oval-shaped leaves with a minty, fragrant smell. Holy Basil also produces tiny flower clusters at the branch terminal—their color ranges from white to magenta, enclosed by purple sepals. The flowers, leaves, seeds, and their extracts are all edible.
