Hivernage: The seeds naturally drop into the sediment and overwinter submerged in the mud until spring.
En pot: It is not suitable for standard containers but can be grown in large, water filled tubs.

Seed propagation

1. Keep harvested seeds moist and cool throughout the winter.
2. Sow seeds directly into the mud of a shallow pond in early spring.
3. Ensure the water depth remains between 15 and 60 centimeters.

Ensure your water source is clean and slow moving to prevent the buildup of pathogens.

Bonnes associations
