If for us Westerners the name of this plant isvetiver, for Indians it isKhus. In this page we will see how to cultivate this plant, the engineering uses of vetiver, its usefulness in preventing soil erosion and hydrogeological instability and its applications in the industrial field.
Thevetiverit can rapidly colonize large areas. Thanks to its very dense and deep root system, it is used in naturalistic engineering to counteract soil erosion. This method is known asVetiver system; the plant in question is used for phytoremediation of water and soil contaminated by heavy metals, hydrocarbons and chemicals.
At an industrial level, essential oil extracted from its roots is also widely used. This oil is widely used in perfumery while Ayurvedic medicine, a traditional Indian medicine, uses the dried roots to treat various ailments. For all the uses listed, we refer you to the dedicated pages:

Description of the plant
Thevetiverit can grow up to 150 cm in height. It has very tall stems and elongated, thin leaves. The leaves are quite stiff and in the flowering period the stems end with purple-brown flowers.
The feature that makes this plant very interesting is represented by the root system: unlike most grasses that develop roots horizontally, the roots of vetiver develop downwards until they reach 2 - 4 meters deep. Vetiver seeds are generally sterile, which is why it is not a weed.
The root system of vetiver is finely structured and very strong. Root development is so rapid that it can reach 3 - 4 meters deep from the first year of cultivation. Thevetiverit has no stolons or rhizomes.
Although it has Indian origins, the plant has been naturalized in different areas of the world. The major producers of vetiver essential oil are Burma, Thailand and Indochina, from this it is assumed that this plant is heavily cultivated in the nations just mentioned.
The vetiverit can also be grown in our local climate even if it is more successful in southern Italy. Thanks to its roots capable of penetrating deeply, thevetiverit is very resistant to drought and can help counteract erosion.
As stated, the most traded and commonly used genotypes forcropsthey are sterile, so for the multiplication clones are exploited that go to form plants identical to the mother plant
When purchasing vetiver plants, be sure to choose a sterile genotype as fertile genotypes are highly invasive. Forcultivate vetiver, know that the plant grows best in full sun.
