Lemongrass (Cymbopogon citratus) is a perennial tropical grass native to South Asia, particularly India and Sri Lanka, widely cultivated across Southeast Asia. The plant grows in dense clumps with long, slender, blade-like leaves that reach 60–90 cm in height. The edible portion consists of the stalks or culms, specifically the pale, tender base and lower stem (typically the bottom 10–15 cm), which contain the most concentrated oils and flavor. The upper green leaves are tougher and more fibrous but valuable for infusions and broths. Lemongrass has a distinctly aromatic, fresh, lemony flavor profile with subtle floral and grassy notes, derived primarily from citral, an essential oil compound similar to lemon zest but more delicate and herbaceous.

The plant's botanical classification places it within Poaceae (grass family), making it botanically distinct from true citrus despite its flavor similarity. Multiple cultivars exist, with East Indian lemongrass (C. citratus) being the most common culinary variety, while West Indian lemongrass (C. flexuosus) is also used in some regions. Fresh branches are the preferred form in most cuisines, though dried leaves and powdered versions are available.

Lemongrass is foundational to Southeast Asian cuisines, particularly Thai, Vietnamese, Cambodian, and Malaysian cooking. The tender stalks are bruised, sliced, or left whole to infuse soups, curries, and broths with their characteristic citrus aroma—Thai tom yum and tom kha gai exemplify this technique. The leaves steep into tea, herbal infusions, and are used to wrap and flavor fish or meat. In Vietnamese cuisine, finely minced lemongrass flavors dipping sauces and marinades; in Malaysian cooking, it features in rendang and laksa. The ingredient also appears in Caribbean and Latin American cuisines, particularly in marinades and beverages. Lemongrass pairs well with coconut milk, chilies, fish sauce, garlic, and ginger, and is typically removed before serving if left in large pieces.
