Agastache rugosa, commonly called Korean-mint or purple giant hyssop, is an aromatic herb in the mint family. Like other members of its family such as basil, peppermint, sage, Korean mint is also aromatic, and medicinally useful. The plant is native to moist grasslands, valleys and stream banks in East Asia (China, Japan, Korea, Russian Primorye, Taiwan, India, and Vietnam). Blue Licorice, Chinese Patchouli, wrinkled giant hyssop, purple giant hyssop, Indian mint, huo xiang, Chinese giant-hyssop, Korean-mint, Korean licorice mint and patchouli herb are few of the popular common names of the plant. Genus name comes from the Greek words agan meaning very much and stachys meaning an ear of wheat in reference to the numerous flower spikes tightly packed with whorls of brightly colored violet flowers. Specific epithet means wrinkled.
