ANISE HYSSOP
Agastache foeniculum
The leaves and tiny lavender-blue flowers of anise hyssop smell and taste of anise, but its square stems and opposite leaves tell you it belongs to the mint family. The leaves look a bit like catnip, but larger.
Herb lovers claim it as a culinary herb, using the fresh or dried leaves in tea and crumbling the tangy flowers over fruit salad. Bees are very attracted to the flowers.
You should not grow basil, carrots or rue near anise.
Anise will disguise the scent of brassica plants (broccoli, cabbage, cauliflower, etc.) and keep away the aphids. It does well near coriander (cilantro), but not dill
