Madagascan Lemongrass plants - Cymbopogon citratus

Madagascar Lemongrass, in Latin Andropogon citratus (synonym Cymbopogon citratus), is a tender perennial grass, of tropical origin, which is mainly cultivated in pots in European climates, allowing it to be within reach during the summer, but also to be protected from cold and humidity in winter. Its deliciously lemon-scented leaves enhance many exotic specialties, especially Thai and Malaysian cuisines. It is also a medicinal plant, used in infusion for its tonic and refreshing properties, as well as in aromatherapy with Lemongrass essential oil. Planting can be done all year round, preferably from May to September.

Madagascar Lemongrass, also known as Gabon Vervain, belongs to the Poaceae family, just like couch grass and bamboo. This perennial plant forms a fairly loose clump of long linear leaves that can reach over a metre in height in a tropical climate, but no more than 70 to 80 cm (28 to 32in) when grown in a pot in our temperate regions. Its pale green leaves are linear, quite sharp, and bulbous at their bases. These are the parts that are consumed, preferably tender and fresh, finely chopped. They add flavour to many Asian dishes, especially Vietnamese ones, such as chicken or shrimp broths.

Madagascar Lemongrass is a very sensitive grass, requiring heat and water during its growing period, from spring to summer. In winter, on the other hand, the plant prefers a relatively dry substrate. Its cultivation in open ground is therefore difficult in our climates. It is mainly grown in pots as its foliage does not tolerate temperatures below 10°C (50°F). Place it outdoors during the summer and, as soon as the first frosts appear, move it indoors to a bright, well-ventilated, and sufficiently warm place (temperature above 10°C (50°F)).

This Lemongrass is sometimes confused with Lemon Verbena or Melissa officinalis, two aromatic plants with lemon scents that are nevertheless quite different.

Harvesting: Cut the leaves from May to October, according to your needs. However, wait until the 3rd or 4th year before harvesting, so that the foliage is sufficiently abundant.

Storage: Lemongrass can be stored for a few days in the refrigerator or for a few months by drying or freezing. However, it is preferable to consume it fresh to fully enjoy its aroma.

The gardener's little tip: In summer, place your pot on the terrace, the lemongrass will keep mosquitoes away!
