Agastache foeniculum is more commonly known as anise hyssop.  This is an upright, clump-forming perennial from the mint family that is native to the upper Midwest and the Great Plains.  You typically find it in prairies, dry upland forested areas, plains and fields.  It grows to a height of 2 to 4 feet tall and is noted for it’s mid to late summer bloom of lavender to purple flowers in terminal spikes and its anise-scented foliage.  Square stems produce ovate to broad-lanceolate dull green leaves (up to 4 inches in length) with toothed margins.

Flowers appear in many-flowered false whorls which are densely packed into showy, cylindrical, terminal flower spikes (3 to 6 inches in length).  Individual, tiny, tubular, two-lipped flowers (each to 1/3 inches in length) have no fragrance.  Flowers are highly attractive to bees, hummingbirds, and butterflies.  Anise hyssop is composed of erect branches of mint-and-licorice-scented, medium green leaves ending in fuzzy spikes of small lavender flowers.

How To Make Anise Hyssop Thrive

Agastache foeniculum is easily grown in average, dry to medium moisture, well-drained soils in full sun to part shade.  Your best results are in full sun.  This plant performs well in moist soils, but good soil drainage is absolutely essential.  Plants tolerate dry soils, particularly once plants are established. Deadheading spent flowers will promote additional bloom.  General Anise Hyssop Information

Garden Uses

This is a great addition to your border gardens, wildflower gardens, herb gardens, butterfly gardens, or meadows.  Flower spikes are also attractive additions to fresh cut or dried arrangements.

  1. Great info of this plant! Very pretty and easy to grow.:)
    I’ll check if I can get the seeds or plants from our local nursery. Thank you, Charlie!

  2. Nothing quite as delicious of the taste of Anise for me ~ great post, and worthy to taste in a tea. 🙂

  3. I do love liquorice tea!

  4. I use to grow this when I had a big garden and why I never made tea I don’t know. Having a more confined garden now I stay away from the mint family even though I love it.

  5. I planted this last season and I just love it. I didn’t know you could make tea..

  6. LIcorice flavored tea? Not sure about that. While I love plants with a licorice fragrance, it is not my favorite flavor to taste. the plant, however, is lovely and has some fine qualities.

  7. We have several of these and absolutely love them both because they’re beautiful and because the bees go crazy over them! Not a fan of anything tasting remotely like licorice but the husband definitely is 🙂

  8. I do love liquorice tea!
