Echinodorus Reni UNS Tissue Culture
Plant Profile
Echinodorus 'Reni' is a dwarf red sword cultivar known for being one of the most compact red species in the Echinodorus family. Reaching between 6 and 15 inches tall, it fits comfortably into midground zones or compact background layouts where larger sword varieties might quickly outgrow their space. Under moderate to high lighting, its foliage undergoes a dramatic color transformation, producing vibrant young leaves in shades of deep wine red and reddish-brown that mature into rich olive green with distinct dark reddish veins. Naturally hardy and undemanding, it offers aquascapers a striking contrast of deep red coloration without requiring high-maintenance care, securing its place as an accessible favorite among aquarium plants for beginners.
Tissue culture cups ensure your aquascape gets a super clean starting point. Lab-grown and fully sterile, it arrives without pests, snails, duckweed, or any unwanted algae. It’s the go-to option for anyone who wants peace of mind when adding fresh greenery to a carefully maintained setup.
Key Features & Notes
- Compact growth habit allows it to fit seamlessly into midground or smaller background zones.
- Striking foliage transitions from deep wine red and reddish-bronze on new growth to rich olive green as it matures.
- A hardy and adaptable species that delivers bold color contrast without requiring complex care regimens.
Care & Planting Instructions
- Prep the plant by carefully removing the plantlets from the cup and rinsing away all sterile nutrient gel under lukewarm, dechlorinated water before mounting.
- 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.
- Provide moderate to high lighting; while CO2 injection isn't strictly required, good lighting will enhance its reddish-brown colors. See our guide to growing red aquarium plants.
- 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 maintain and enhance the deep wine-red color on my Echinodorus 'Reni' tissue culture plant?
Provide moderate-to-high lighting and supply adequate iron and substrate nutrients via root tabs. Higher light levels encourage new emerging leaves to develop intense wine-red and deep reddish-brown tones rather than fading to green.
2. Is Echinodorus 'Reni' suitable for midground placement or smaller aquariums?
Yes, 'Reni' is one of the smallest dwarf red sword cultivars available, topping out between 4 and 15 inches. Unlike massive Amazon Swords that quickly overwhelm small setups, its compact size makes it ideal for midground focal points in medium tanks or background placement in nano aquariums.
3. How do I prepare and divide tissue culture portions of Echinodorus 'Reni'?
Gently wash off the clear nutrient gel under room-temperature water. Using your fingers, carefully separate the dense clump into individual plantlets, then anchor their roots into nutrient-rich soil with fine-tipped tweezers, keeping the growth crown exposed above the substrate line.
