Khus

Chrysopogon zizanioides, commonly known as vetiver and khus, is a perennial bunchgrass of the family Poaceae. Vetiver is most closely related to sorghum while sharing many morphological characteristics with other fragrant grasses, such as lemongrass (Cymbopogon citratus), citronella (Cymbopogon nardus, C. winterianus), and palmarosa (Cymbopogon martinii).
