Preferred from the year-round summer-like climate of Dambulla, Sri Lanka, which experiences a tropical monsoon climate with an average annual temperature of 28℃. Located in Dambulla, Sri Lanka, it offers the sticky loamy soil that Vetiver prefers, along with a rich variety of plant species in the mountainous region.

Vetiver derives from the Tamil word "Vetiverr," meaning "to cut with an axe." Its leaves resemble those of a reed, often forming dense clusters. Vetiver has upright stems with numerous branching, soft and resilient rhizomes (rootstalks) that firmly anchor the plant and contribute to its strength derived from the soil. It is considered a "herbaceous plant with a long root system" as its deep roots can reach lengths of 3 to 4 meters underground.

As a result, the collection and extraction process of Vetiver essential oil are complex and time-consuming. Harvesting workers need to manually dig the extensive root system underground, thoroughly clean them, and then cut them into shorter lengths for drying in a cool place for 1-2 days to enhance the richness of the extracted oil.
