Description
Plant Profile
Echinodorus grandifolius is known for its massive scale and broad, heart-to-oval-shaped bright green foliage. Unlike many faster-growing sword cultivars, this giant species develops at a steady, moderate pace, allowing aquascapers to enjoy its substantial structure without constantly trimming back runaway growth. Reaching heights of 10 to 20+ inches, its expansive leaf blades naturally draw the eye, making it a commanding focal point across background zones in larger aquariums. Thanks to its low lighting demands and forgiving nature, even tolerating cooler, unheated water temperatures, it serves as a hardy, low-maintenance option for beginners.
Key Features & Notes
Large, heart-shaped leaf blades create a commanding focal point in medium-to-large aquariums.
Slower, steady growth rate compared to other sword varieties makes size management far easier.
Adaptable nature allows it to thrive in low lighting and unheated setups without mandatory CO2 injection.
Care & Planting Instructions
Prep the plant by removing it from the pot and clearing all rockwool from the roots.
Plant the roots deeply into your aquarium soil, keeping the crown of the plant resting just above the substrate line to prevent rot.
All Echinodorus are heavy root feeders that rely on rich substrate nutrition; placing root tabs near the base supports steady, healthy leaf development.
Supplemental CO2 injection accelerates growth and encourages denser, fuller foliage, though the plant will still grow steadily in low-tech setups.
Maintain stable water parameters to prevent leaf shedding during the initial transition period.
Final size and coloration depend entirely on your specific aquarium conditions; please note that photos are a representation, and individual plants may vary.

Frequently Asked Questions
1. How do I prune an Echinodorus when it grows too large?
Prune older or overgrown outer leaves individually near the root crown using sharp aquascaping scissors. Avoid cutting across leaf blades, as damaged leaf tips will turn brown rather than regrowing.
2. Can this background plant grow in low-tech aquariums without CO2?
Yes, this species thrives in low-tech aquariums without pressurized CO2, provided it receives adequate root supplementation and consistent lighting.
3. Why are the leaves on my new Echinodorus melting or turning yellow?
Sword plants are often grown emersed and shed their old emersed leaves when submerged to adapt to underwater growth. Keep water parameters stable and supply root tabs near the base to support new leaves.
