About

Cymbopogon citratus, commonly known as West Indian lemon grass or simply lemon grass, is a tropical plant native to South Asia and Maritime Southeast Asia and introduced to many tropical regions.

Cymbopogon citratus is often sold in stem form. While it can be grown in warmer temperate regions, it is not hardy to frost.

Where it grows

Cymbopogon citratus is native to South Asia and Maritime Southeast Asia (Malesia). After World War I, lemongrass was introduced to Madagascar, South America, and Central America. It has now been naturalized throughout the tropics and subtropics worldwide.

Uses

Cymbopogon citratus is abundant in the Philippines and Indonesia where it is known as tanglad or sereh, respectively. Its fragrant leaves are traditionally used in cooking, particularly for lechon and roasted chicken.
