Patchouli (Pogostemon cablin (Blanco) Benth; also patchouly or pachouli) is a species of plant from the genus Pogostemon. It is a bushy herb of the mint family, with erect stems, reaching two or three feet (about 0.75m) in height and bearing small, pale pink-white flowers. The plant is native to tropical regions of Asia, and is now extensively cultivated in China, Indonesia, India, Malaysia,Mauritius, Taiwan, the Philippines, Thailand, and Vietnam.

Patchouli grows well in warm to tropical climates. It thrives in hot weather but not direct sunlight. If the plant withers due to lack of water, it will recover well and quickly after rain or watering. The seed-producing flowers are very fragrant and blossom in late fall. The tiny seeds may be harvested for planting, but they are very delicate and easily crushed. Cuttings from the mother plant can also be rooted in water to produce additional plants.
