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.

Korean Mint is an upright, clump-forming, herbaceous perennial plant that grows about 40–100 cm (16–39 in) tall. The plant is found growing in grassy places in mountains, especially by streams, and in valleys. The plant does best in dry, well-drained soil, and prefers soil rich in organic matter, and neutral ph. Oval-cordate leaves are oppositely arranged, 5–10 cm (2–4 in) long and 3–7 cm (1 1⁄4–2 3⁄4 in) broad, with coarsely serrated margins. Some leaves have hair and/or touches of white on the underside.

Purple bilabiate flowers bloom in verticillasters that are 5–15 cm (2–6 in) long and 2 cm (3⁄4 in) broad. The calyx is 5–6 mm (0.20–0.24 in) long, with five narrow triangular lobes. Petals are 8–10 mm (0.31–0.39 in) long, lower ones longer and the ones inside serrated. The stamens are didynamous, long, and exposed. Flowering normally takes place from July to September. Fertile flowers are followed by schizocarp, with obovate elliptical mericaps of 1.8 mm (0.071 in).
