Description
Plant Profile
Reaching impressive vertical heights, Echinodorus ‘Impai’ is an outstanding Amazon Sword variety tailored for creating dense, jungle-style backgrounds in larger displays. Characterized by its light green, elliptic leaves that taper into pointed tips, this tall-growing rosette plant produces broad, slightly wavy foliage with prominent leaf veining that catches aquarium lighting beautifully. Its architectural silhouette acts as an ideal backdrop anchor, concealing background equipment like filter pipes or heaters. Extremely hardy and forgiving across a wide range of water conditions, it delivers classic sword plant volume and lush green color without demanding complex high-tech maintenance.
Key Features & Notes
Tall, light green elliptic foliage provides impressive scale and lush vertical structure for background zones.
Broad, slightly wavy leaves with prominent veins create a classic, jungle-like background canopy.
Hardy and adaptable rosette species that thrives across various tank conditions without requiring CO2.
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 central crown 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.
Sword plants propagate through side shoots off of their leaves, which can be trimmed and replanted into the substrate. To control the size of your sword plant, you can remove the side shoots and older leaves.

Frequently Asked Questions
1. How do I prevent Echinodorus ‘Impai’ from shading other plants as it grows tall?
Because its light green, elliptic leaves can expand up to 20+ inches, regularly prune older or larger outer leaves near the root crown using sharp aquascaping scissors. This keeps the rosette contained and ensures light reaches lower foreground plants.
2. Can Echinodorus ‘Impai’ thrive in low-tech setups without CO2?
Yes, it grows vigorously in low-tech aquariums without pressurized CO2. Providing a nutrient-rich substrate or inserting root tabs near the base, along with moderate lighting, is all it needs to maintain lush green growth.
3. Will Echinodorus ‘Impai’ produce flowers if grown emersed?
Yes, when grown in open-top aquariums, paludariums, or emersed setups, tall flowering stalks can emerge above the waterline to produce charming small white blossoms.
