Agastache foeniculum, or licorice mint, is a perennial that supplies nectar for Skippers and other butterflies. The Cree, Cheyenne and Lakota used it as medicine. It grows from 60–120 cm high with edible flowers. This is one of the few mints that is not invasive. The white form matures two weeks later than the blue but has a more subtle flavour for tea and salads.
