I do adore Italian food, and this herb is one of the reasons, the other being garlic!
Even Bunnings offers three varieties
Thai Basil (first photo)
Sweet Basil (bottom photo), and
Holy Basil, which I did not purchase.
Herbs in the garden have an unexpected role. I often meander along the pathways with Juliet in my arms. I tell her the name of the herb, and then suggest that she smells it. Sweet Basil is particularly good for this.
Basil was Manuel's pet rat, in Season 2, Episode 6, of "Fawlty Towers", October 1979.
