Lemongrass oil is produced from two distinctly different species of Cymbopogon. C. citratusand C. flexuosus are tufted perennial grasses with numerous stiff stems arising from a short rhizomatous rootstock.1 C. flexuosus is a native of India and C. citratus is possibly a native of Sri Lanka. C. citratus is widely cultivated all over the world and has been named West Indian lemongrass.
