Dennerle - Helanthium tenellum 'Red' is available for pre-order – please confirm stock before ordering!
Introduction:
Helanthium tenellum 'Red', often referred to as Red Pygmy Chain Sword, is a striking foreground carpeting plant known for its slender, grass-like leaves that display warm reddish tones under optimal conditions. Formerly classified under the genus Echinodorus, this cultivar is native to North and Central America and has become a favorite in aquascaping due to its low profile, spreading habit, and rich coloration. When provided with strong light and COâ‚‚, the green blades shift to vibrant hues of red and bronze, creating a natural, meadow-like effect. This tissue culture form ensures a clean, algae- and pest-free start, ideal for delicate carpet establishment.
Care Requirements:
Water Parameters:
Temperature: 20–28°C
pH Range: 6.0–7.5
Hardness: Soft to moderately hard water (2–12°dGH)
Nutrient Requirements:
Helanthium tenellum 'Red' requires a nutrient-rich substrate to support its carpet-like spread. Root tabs can enhance growth if nutrients are limited in the substrate. COâ‚‚ injection is highly recommended to bring out its red coloration and to promote a compact, lush carpet. Regular dosing of liquid fertilizers will further support strong leaf development and overall vigor.
Tank Setup:
Ideal for the foreground of both small and large aquariums, this plant thrives in fine gravel or aquasoil. High lighting is essential to induce red coloration and maintain a short, compact growth form. A gentle water flow helps distribute nutrients evenly and prevents detritus buildup within the dense carpet.
Care Tips:
After planting tissue culture specimens, allow them time to adjust to submerged conditions. Trim back initial tall or melt-prone growth to encourage fresh runners. With proper light, COâ‚‚, and nutrients, Helanthium tenellum 'Red' will quickly send out runners, forming a dense, colorful mat. Avoid shading from taller plants to maintain its vibrant tones and growth habit.
Helanthium tenellum 'Red' is a beautiful and rewarding choice for aquascapers aiming to create vibrant, naturalistic foregrounds. Its warm reddish hues and fine texture add depth and contrast, making it a standout plant in both high-energy and nature-style aquascapes.
