Injipullu (Cymbopogon citratus)
Cymbopogon citratus is native to Island Southeast Asia (Malesia). It has been introduced extensively to South Asia since precolonial times. After the World War I, lemongrass was introduced to Madagascar, South America, and Central America. It has now been naturalized throughout the tropics and subtropics worldwide.
Cymbopogon citratus is often sold in stem form. While it can be grown in warmer temperate regions, such as the UK, it is not hardy to frost.
