Agastache foeniculum ‘Get Riehl’ comes from an early 1990s trip when I visited Iowa City plantsman, Frank Riehl. Sharing a love of native habitats, Frank took me to a nearby prairie remnant where I first saw anise hyssop growing in the wild. Those cutting-grown plants have remained in our garden for over two decades, so we decided that it was time to share. The deciduous Agastache foeniculum ‘Get Riehl’ makes a wispy upright clump of angular branched stems, topped from early summer through September with 6″ terminal soft lavender flowers. Agastache foeniculum is also grown for its wonderfully fragrant licorice-scented foliage. Anise hyssop has long been prized for its medicinal value to cure everything from coughs to diarrhea. Bees also use anise hyssop to make a lovely flavored honey. In the garden, good drainage seems to be the key to persistence.
