While Agastache or Anise Hyssops is often grown in perennial gardens it is actually an herb. It grows up to 3 feet in height and is covered with purple or pink flowers in the summer. It is a perennial in garden zones 5 to 9 but generally only comes back for several seasons. However, it is a prolific self-seeder and if it finds a place that it likes will come back for many years. It prefers rich, moist soil conditions in full sun and its leaves and flowers both have a licorice scent and can be steeped into a pleasant tasting tea. They also make an interesting dried flower and are a magnet for honeybees and Agastache other pollinators.
