Scientific Name: Echinodorus tenellus 'Broad Leaf'
Common Name: Broad Leaf Chain Sword, Broad Leaf Pygmy Chain Sword
Origin: Cultivated variety of Echinodorus tenellus (now often classified as Helanthium tenellum)
Growth Rate: Moderate to Fast
Difficulty Level: Easy
Temperature: 20–28°C
pH: 6.0–7.5
GH: 2–15 dGH
KH: 1–8 dKH
Moderate to high lighting is recommended.
Higher light intensity promotes compact growth and dense carpet formation.
Under lower light conditions, leaves become taller and more upright.
CO₂ supplementation is beneficial but not essential.
Encourages faster runner production, denser coverage, and improved overall growth.
Suitable for both low-tech and high-tech planted aquariums.
Primarily a root-feeding plant.
Benefits greatly from nutrient-rich substrates and root tab supplementation.
Requires adequate nitrate, phosphate, potassium, and micronutrients for healthy development.
Regular fertilization supports vigorous growth and lush green foliage.
Best suited for the foreground to midground.
Ideal for creating grass-like carpets and natural meadow effects.
Can also be used around rocks and driftwood to soften hardscape transitions.
Propagates readily through runners.
Daughter plants form along runners and can be separated once established.
Spreads quickly under favorable conditions to form dense colonies.
Trim older or excessively tall leaves to maintain a neat appearance.
Plant individual plantlets with spacing to allow natural spreading.
Nutrient-rich substrate significantly improves growth rate and carpet density.
Stable lighting and fertilization encourage compact growth.
Echinodorus tenellus 'Broad Leaf' is a versatile foreground plant valued for its broader grass-like leaves and attractive carpet-forming growth. It thrives under stable water conditions with moderate to high lighting and adequate nutrient availability. CO₂ supplementation promotes faster growth, denser coverage, and improved overall health. The plant is commonly used in the foreground, where it forms a lush, natural-looking carpet that enhances depth and perspective within Nature, Dutch, and contemporary planted aquariums.
