Echinodorus uruguayensis is a large sword plant from South America with distinctive narrow, ribbon-like leaves that ripple and sway gracefully in aquarium current. The long, elegant leaf form sets it apart from the broader-leafed Echinodorus species, giving it a light and airy quality while still providing substantial visual presence at the back of a planted aquarium.

It is an undemanding species, tolerating a wide range of water conditions and growing well under medium light without CO2 supplementation. Like all Echinodorus it relies heavily on its root system for nutrition, so planting in a nutrient-rich substrate or adding root tabs near the base gives the best results.

Supplied as an established potted plant, Echinodorus uruguayensis can reach 40–60 cm in height and suits aquariums of 200 litres or more. Used in the background, its rippling narrow leaves create a striking contrast against broader-leafed plants and add movement and flow to the planted composition.
