About Citronella grass
Cymbopogon nardus, commonly known as Citronella Grass, is an aromatic perennial grass native to tropical Asia. It is characterized by its long green leaves and distinctive citrus aroma, released when rubbed. It's ideal for pots on patios and balconies, or as an insect-repelling plant in the garden.
Native range
Tropical Asia, likely India and Sri Lanka.
Care tips
It prefers full sun exposure for optimal growth and increased aromatic oil production. Watering should be regular, keeping the soil moist but not waterlogged, especially in warm climates. Use a well-draining substrate; a universal potting mix with some sand works well. Avoid frost, as it is sensitive to cold and may die if temperatures drop too low.
