harvest away... flowers are tasty too when they are young... avoid whacking more than half the plant at a time if possible...

Taste before using. African Blue Basil is stronger- and more camphory-tasting than ordinary sweet basil. You may want to use it sparingly or combine it with other herbs like parsley. Not an ideal choice for pesto, IMO.

true that... i use it more akin to how i use thai basil than italian...

my buddy has glazed the young blossoms and used them to dress up a lemongrass vanilla cupcake as well...
