The African Blue basil is an accidental hybrid of East African basil and a garden variety called dark opal. African Blue basil leaves are purple and as they mature, they fade to a dark green with purple flecks.
The African Blue basil has a clove-like taste and smell, and has a stronger flavour than regular basil. This distinct flavour makes it an excellent addition to salads, soups or cocktails where it lends a depth of flavour.
