✂️ Care

Plant the bulb in a nutrient-rich substrate — the bulb should partially protrude above the substrate to prevent rot. The plant grows quickly and forms long leaves that continue to grow on the water surface. Regularly remove dead leaves. The plant forms side bulbs for propagation.

💡 Planter's tip

Ideal for larger aquariums as an impressive background plant. The long, elegant leaves give a tropical, lush effect. Combines beautifully with broad-leaved species such as Echinodorus or Cryptocoryne for a varied background zone.
