Cymbopogon, also known as lemongrass, barbed wire grass, silky heads, Cochin grass or Malabar grass or oily heads, is a genus of Asian, African, Australian, and tropical island plants in the grass family.
Cymbopogon citratus, commonly known as West Indian lemon grass or simply lemon grass, is a tropical plant native to 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, such as the UK, it is not hardy to frost. Cymbopogon citratus is native to Island Southeast Asia (Malesia). It has been introduced extensively to South Asia since precolonial times. Cymbopogon citratus is abundant in the Philippines and Indonesia where it is known as tanglad or sereh. Its fragrant leaves are traditionally used in cooking, particularly for lechon and roasted chicken. The dried leaves can also be brewed into a tea, either alone or as a flavoring in other teas, imparting a flavor reminiscent of lemon juice but with a mild sweetness without significant sourness or tartness.
