Additional Care Tips

Maintain consistent water levels, ensuring the plant is fully submerged. The rhizome should be planted in soil at the bottom of the pond or container, with water covering it by at least 15-30 cm.

Remove spent flowers and yellowing leaves to encourage new growth and maintain a tidy appearance. Trim back any excessively long or damaged foliage. Pruning is generally minimal for this aquatic species.

Propagate by division of rhizomes in spring. Each division should have at least one growing point. Seeds can be sown in warm water, but division is more common and reliable for established plants.

Repotting is typically done every 2-3 years in spring, or when the plant outgrows its container. Use a large, heavy pot filled with heavy loam or clay soil, ensuring the rhizome is planted horizontally with growing tips pointing upwards.
