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 watering, it will recover well and quickly after it has been watered. The seed producing flowers are very fragrant and bloom 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.
The heavy and strong scent of patchouli has been used for centuries in perfumes, and more recently in incense, insect repellents, and alternative medicines.
