“Bio Mizukusa No Mori” in-vitro cup plant, Helanthium Tenellum.

• Grasslike ground-covering plant
• Light to medium green colours
• Not very demanding
• M cup

This light green lawn-forming Helanthium (Chain sword) is great for aquascaping. It is also sold under the names Echinodorus tenellus, E. tenellus “Green” and Helanthium tenellum.

The plantlets are best planted into the substrate individually at a small distance. Under strong light (ideally 0.5 watts/litre or more) and a good nutrient and CO₂ supply the plant will readily reproduce by forming long runners with many plantlets. Should it grow too fast, just cut off the new runners. If the lawn has grown too dense you ought to thin it from time to time.

Sterile cultivated aquatic plant, free from algae, parasites, germs and foreign plants. The sterile cups are available in two sizes, S and M. Where the bottoms of the cups have the same diameter, the M cup is significantly taller to allow higher-growing plants to develop properly.
