Agastache foeniculum [blue giant hyssop], commonly called anise hyssop, is a species of perennial plant in the mint family (Lamiaceae). This plant is native to much of north-central and northern North America.
Anise hyssop was used medicinally by Native Americans for cough, fevers, wounds, diarrhea. The soft, anise-scented leaves are used as a seasoning, as a tea, and in potpourri. The purple flower spike is favored by bees which make a light fragrant honey from the nectar.
