Agastache became only recently wider known in Europe, but yet it bears a lot of common names: Korean Mint, Bubble Mint, Anise Hyssop and some more. Unfortunately the common names mix up the genera and you can tell from them to which genus the actual plant belongs. Since many nurseries use names made up by themselves the confusion is complete unless the correct botanical name is given, too.  `Liquorice Blue` is a plant for sonny spots in your garden. From Midsummer on it bears long blue flower spikes and makes a very good cut flower. Its large leafs bear a scent that is a mixture of mint and liquorice. You can use them fresh or dried for herbal teas.
