- Growing Difficulty
- Intermediate
- Lifespan
- Perennial
- Size
- 10-30cm
- Watering
- Root tabs, CO2
- Lighting
- Relatively easy to grow with medium to strong light. Adequate light keeps the leaves light green to yellow-green.
- CO2 & Fertilizer
- CO2 injection is assumed; on top of substrate fertilizer, regular liquid fertilizer containing iron brightens the leaf colour. Nutrient demand is fairly high.
- Water Temperature & Quality
- The optimal water temperature is 18–26°C. It dislikes high temperatures, so take care in tanks that heat up easily.
- Trimming & Propagation
- Trim while adjusting the height in the mid- to background to form a dense bush. Cut stems can be replanted to propagate.
- Cautions
- A dimorphic plant that grows both submersed and emersed. Switched to emersed culture, it produces deep red flowers on slender stems.
