Planting and Propagation

• Planting: Bury the roots fully in the substrate while keeping the central crown (where leaves sprout) completely above the surface to prevent crown rot.
• Propagation: Reproduces naturally by sending out horizontal runners that generate small adventitious plantlets, or via flower stalks when grown emersed.

This versatile and hardy plant is an excellent choice for both beginners and experienced aquarists, adding a lush, vibrant touch to any freshwater aquarium.
