Helanthium tenellum ‘Madeira – IC352

Helanthium tenellum ‘Madeira’ is a beautiful carpeting aquatic plant that is popular in freshwater planted aquariums. It’s a compact variant of Helanthium tenellum (formerly Echinodorus tenellus) and is known for its reddish-brown to green narrow leaves, depending on light and nutrients.

Foreground carpeting: Ideal for creating a lush green or reddish-brown carpet in the front of the tank.

Dutch or Nature-style aquascapes: Adds texture and contrast to wood, rocks, and other plant types.

Low-tech tanks: Can still thrive with moderate light and good substrate even without CO₂.

Propagation: It spreads by sending out runners that form new plants — let them grow or replant them manually.

Care Tips

Lighting Provide moderate to high lighting for compact, reddish growth.

Substrate Fine-grain, nutrient-rich substrate is best (e.g., aquasoil or root tabs).

CO₂ Injection Optional but promotes faster, denser carpet growth.

Trimming Trim regularly to maintain a tidy carpet and encourage lateral runners.

Nutrients Root tabs or a complete liquid fertilizer help maintain vibrant growth.

Water parameters pH: 6.0 – 7.5, Temp: 20–28°C, Soft to moderately hard water.
