-->{{Treatment/Body
|discussion=<p><i>Chrysopogon zizanioides</i>, which used to be included in Vetiveria, is native to river banks and flood plains in the south Asian tropics and subtropics, but it has been deliberately established in the warmer areas of the United States. It grows in a variety of soils, from heavy clays to dune sand, and will tolerate windy coastal conditions.</p><!--
--><p>Hedges of <i>Chrysopogon zizanioides</i> can control soil erosion or restore eroded land. Once established, they are effective even in desert areas subject to flash flooding. The deep root system reaches water far below the surface and prevents the plants from being washed away while the dense, aboveground growth traps silt and sediment. Because <i>C. zizanioides</i> does not spread vegetatively and many cultigens have low or no seed production, contour hedges can be planted around cultivated fields or engi-hedges can be planted around cultivated fields or engineering structures without fear of invasion. Essential oils from the aromatic roots are sometimes used as perfume, and numerous biocidal effects are reported. For current information on uses of <i>Chrysopogon zizanioides</i>, see http://www.vetiver.org/.</p>
