Cymbopogon flexuosus, commonly known as East Indian lemongrass or Cochin grass, is a tropical perennial grass native to Southeast Asia. It is prized for its aromatic leaves and stems used in Asian cuisine, traditional medicine, and essential oil production. The species requires warm, consistent temperatures and light to germinate successfully, with seeds typically emerging within 7-40 days under optimal conditions.

What to expect
Tips
Ensure seeds are pressed firmly onto the soil surface and barely covered as they require light for germination. Maintain constant high humidity using a humidity dome or clear plastic cover. Keep soil temperature between 20-30°C (68-86°F), ideally with bottom heat. Do not overwater; substrate should be moist but not soggy. Once germinated, provide 12-16 hours of bright light daily. Gradually remove humidity cover after sprouting to acclimate seedlings. Transplant to individual pots when seedlings are large enough to handle. Acclimate to outdoor conditions before transplanting outdoors after all frost danger has passed.
