Chrysopogon zizanioides, commonly known as vetiver (derived from the Tamil: வெட்டிவேர் vettiver) is a perennial grass of the Poaceae family, native to India. In western and northern India, it is popularly known as khus.  

Vetiver can grow up to 1.5 metres high and form clumps as wide. The stems are tall and the leaves are long, thin, and rather rigid; the flowers are brownish-purple. Unlike most grasses, which form horizontally spreading, mat-like root systems, vetiver’s roots grow downward, 2–4 m in depth.  
Vetiver is most closely related to Sorghum but shares many morphological characteristics with other fragrant grasses, such as lemongrass (Cymbopogon citratus), citronella (Cymbopogon nardus, C. winterianus), and palmarosa (Cymbopogon martinii). Though it originates in India, vetiver is widely cultivated in the tropical regions of the world. The world’s major producers include Haiti, India, Java, and Réunion.  
The most commonly used commercial genotypes of vetiver are sterile (do not produce fertile seeds), and because vetiver propagates itself by small offsets instead of underground stolons, these genotypes are noninvasive and can easily be controlled by cultivation of the soil at the boundary of the hedge. However, care must be taken, because fertile genotypes of vetiver have become invasive.[2]  
Vegetatively propagated, almost all vetiver grown worldwide for perfumery, agriculture, and bioengineering has been shown by DNA fingerprinting to be essentially the same nonfertile cultigen (called ‘Sunshine’ in the United States, after the town of Sunshine, Louisiana).[3] 
The vetiver grass has a gregarious habit and grows in bunches. Shoots growing from the underground crown make the plant frost– and fire-resistant, and allow it to survive heavy grazing pressure. The leaves can become up to 120–150 cm long and 0.8 cm wide.[5] The panicles are 15–30 centimeters long and have whorled, 2.5–5.0 centimeters long branches.[5] The spikelets are in pairs, and there are three stamens.
The plant stems are erect and stiff. They can persist deep water flow. Under clear water, the plant can survive up to two months.
The root system of vetiver is finely structured and very strong. It can grow 3–4 m deep within the first year. Vetiver has no stolons nor rhizomes. Because of all these characteristics, the vetiver plant is highly drought-tolerant and can help to protect soil against sheet erosion. In case of sediment deposition, new roots can grow out of buried nodes.
Vetiver grass is grown for many different purposes. The plant helps to stabilise soil and protects it against erosion, but it can also protect fields against pests and weeds. Vetiver has favourable qualities for animal feed. From the roots, oil is extracted and used for cosmetics, aromatherapy , herbal skincare and ayurvedic soap . Due to its fibrous properties, the plant can also be used for handicrafts, ropes and more.

dig some roots it has nice aroma

I have read about the scented roots of Chrysopogon zizanioides (L.). But it was not possible to dig the roots. It was beside a rail-line and there was human … everywhere! I will have to find the grass somewhere else.


I took a herbarium of this grass to BSI Shibpur today. It has been identified as Chrysopogon zizanioides (L.), though authentication could not be done with seal & signature because i didn’t maintain proper protocol.

This is possibly the same specimen as in efi thread


Yes it is. Also called Vetiveria zizanoidesKhus

The roots being aromatic are used in air coolers and hand fans and also for aromatic oil. 


Thank you … Incidentally I have recorded a few images today, though from a distance!
