What is Ceylon lemongrass?
Ceylon lemongrass is a variety of aromatic plant native to Sri Lanka (formerly Ceylon), renowned for its delicately lemony fragrance. Belonging to the Poaceae family, it takes the form of long, fibrous stems, whose aroma is mainly found in the lower part, where the stem is thickest. Its Latin name, Cymbopogon nardus, distinguishes it from other lemons, such as Java citronella, and gives it specific virtues, appreciated in cooking, cosmetics and aromatherapy.
Where does Ceylon citronella come from?
Native to the island of Ceylon, now known as Sri Lanka, Ceylon lemongrass thrives in a warm, humid tropical climate. Rich, well-drained soils, combined with heavy rainfall, provide ideal conditions for this hardy plant. Over time, it has spread to other parts of Asia, such as India and parts of Southeast Asia, where it is particularly appreciated for its aromatic qualities and varied applications.
What does it look like?
Ceylon lemongrass resembles other varieties of lemongrass, with its long, grayish-green blade-shaped leaves and stems forming small bulbs at the base. However, its scent is sometimes considered more delicate and slightly more floral than that of Java lemongrass. Stems generally reach heights of 1 to 1.5 meters. Cutting through the stem reveals fibrous layers, the softest part of which lies towards the base, the area most used in cooking.
What are its main constituents?
- Essential oils: Ceylon lemongrass is rich in geraniol and citronnellal, compounds that give it its characteristic fragrance and repellent action on certain insects.
- Antioxidants: Various polyphenols help protect the body against oxidative stress.
- Fiber: The stalk contains fiber, which is good for transit, although in practice it is often removed from the preparation before tasting.
- Minerals: significant quantities of potassium and magnesium can be found in the stem, although consumption remains moderate.
