Botanical Description

Lemongrass is a tall, perennial grass with long, narrow, blade-like leaves that have a sharp, lemony scent when crushed. It typically grows 1–2 meters in height and forms dense clumps. The leaves are light green, and its stems are fibrous, holding essential oils that give it a refreshing aroma.

Habitat and Distribution

Native to tropical and subtropical Asia, lemongrass is now cultivated in India, Sri Lanka, Africa, South America, and Australia. It thrives in warm, sunny climates with well-drained soils and is often found in grasslands or cultivated fields.

Biological Importance

• Pollinator Friendly: While it’s wind-pollinated like most grasses, its flowers can attract small insects.

• Soil Health: Lemongrass roots help prevent soil erosion.

• Pest Repellent: The plant produces compounds like citral, which repel mosquitoes and other insects.

Chemical Composition

The essential oil from lemongrass contains:

• Citral – responsible for its strong lemon scent and antimicrobial properties.

• Geraniol – contributes to fragrance and repels insects.

• Myrcene – has analgesic (pain-relieving) properties.

Medicinal and Cultural Uses

• Medicinal: Traditionally used to relieve digestive issues, reduce fever, and aid relaxation. In modern herbal medicine, lemongrass tea is popular for its soothing effects.

• Culinary: A common ingredient in Southeast Asian cuisine, adding flavor to soups, curries, and teas.

• Aromatherapy: Its oil is used in diffusers for stress relief and air purification.

Propagation and Cultivation

Lemongrass is usually propagated by division of clumps, not by seed. For healthy growth:

• Provide full sun exposure.

• Use loamy, well-drained soil.

• Water regularly but avoid waterlogging.
