Cymbopogon citratus, commonly known as lemongrass, is a perennial tropical grass cultivated for its aromatic leaves.
It is widely cultivated for its intensely aromatic leaves, which release a strong lemon scent when crushed, making it highly valued both for culinary and medicinal uses.
This grass forms tall, dense clumps, often reaching heights of one to two meters.
Its long, narrow leaves grow upright from the base, creating a striking, grassy mound.
Small, inconspicuous flowers appear at the tips of the stems, though they are rarely of interest because the plant is primarily grown for its leaves and essential oils.
Cymbopogon citratus grows best in well-drained, fertile soil with a slightly acidic to neutral pH and prefers full sun exposure.
While it requires regular watering to establish, it is quite drought-tolerant once mature.

The Tales & The Botany: Cymbopogon citratus
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.
Lemongrass is widely used in Southeast Asian cuisine, adding its distinctive citrus flavor to teas, soups, curries, and marinades.
But beyond the kitchen, it has uses in traditional medicinal uses – a calming tea, a digestive aid, and a mild fever reducer.
Many of the perfumes or aromatherapy kits on the market have a note of lemongrass in them as well.
On top of all of that, it is an extremely efficient natural insect repellent.
Citronellol is an essential oil constituent from Cymbopogon citratus, Cymbopogon winterianus, and Lippia alba.
Citronellol has been shown to lower blood pressure in rats by a direct effect on the vascular smooth muscle leading to vasodilation > indicating a possibility that this study can be reproduced in humans.
