✂️ Care
Let the plant float freely or plant it loosely in the substrate — it does not need roots. The plant grows quickly and regularly forms side shoots. Prune regularly to prevent overgrowth; broken parts will grow into new plants.
💡 Planter tip
Ideal for new ponds and aquariums — its rapid growth absorbs excess nutrients and helps prevent algae growth. Provides excellent hiding places for young fish and shrimp.
