Agastache (pronounced AG-a-stak-ee) has been chosen as Herb of the Year 2019. This name is actually the plant genus and includes many different species native to North America. All species attract bees and butterflies and deer do not usually eat. The plant we are most familiar with is Anise Hyssop (Agastache foeniculum) which has a strong anise or licorice fragrance to its leaves. It is a prairie plant that likes sun and grows 3′- 5′ tall in any type soil as long as it is well drained. Anise Hyssop has average moisture requirements and is a perennial herb zone 4. Bloom time is mid summer and common flower colour is purple, but it can be found in white and pink. The native strains can reseed, but you can find sterile cultivars like Blue Fortune which may need support. Use the leaves in teas, green salads, or fruit salads. The flowers are edible also. You can use as cut flowers or dry the flowers for arrangements.
(Agastache scrophulariifolia is known as Purple Giant Hyssop and is similiar to Anise.
Agastache nepetoides is the native Yellow Giant Hyssop or Catnip Giant Hyssop that grows in forests which blooms yellow in summer and grows 2′ to 8′. It is rare in southern Ontario, being more common in the eastern states.
Other varieties of Agastache are Korean Mint (Agastache rugosa) which is zone 6 and Rose Mint or Mexican (Agastache pallidiflora) which is zone 7.
