Summary

Agastache rugosa, commonly known as Korean Mint or Purple Giant Hyssop, is a deciduous perennial herb native to East Asia, thriving in open woodlands and grasslands. It typically grows to a height of 40–100 cm (16–39 in) and features square stalks that branch at the upper part. From July to September, it produces showy spikes of purple bilabiate flowers, with petals measuring 8–10 mm (0.31–0.39 in) in length; the lower petals are longer and the inner ones are serrated. The flowers range in color from rose to violet and are attractive to pollinators such as bees and butterflies.

Korean Mint is valued for its aromatic foliage and flowers, which are used in herbal teas and traditional medicine. It is also appreciated for its ornamental qualities in garden borders and as a naturalizing plant. It requires fertile, moisture-retentive soil and performs best in full sun to part shade. While it prefers consistent moisture, it is relatively drought-tolerant once established. Propagation is typically done by sowing seeds in spring or by root division in autumn or early spring, spacing the plants about 30 centimeters (12 inches) apart. Potential problems include powdery mildew and rust, especially in humid conditions. To maintain plant health, provide good air circulation and avoid overhead watering.CC BY-SA 4.0
