Egeria Najas: ultra-fast-growing oxygenating plant
Egeria najas is a little-known cousin of elodea (Egeria densa), but it is even more robust and vigorous. It grows at an impressive rate, absorbing nitrates and phosphates and thereby strongly limiting algae growth by starving them. It also acts specifically against cyanobacteria thanks to its natural antibiotic molecules with antibacterial properties.
Versatile and hardy, it adapts to many conditions: soft or hard water, varying pH, low or intense light, herbivorous fish, snails... It oxygenates the water abundantly—you can even see it "bubbling"!—thereby contributing to the overall health of the ecosystem.
An extremely effective natural water-purifying and algae-fighting plant, perfect for ponds, aquariums, and tub ponds.
Why choose Egeria najas?
- 🚀 Express growth: up to several centimeters per day!
- 🛡️ Excellent natural water purification and effective control of algae and cyanobacteria
- ⚖️ Tolerates a wide range of water parameters
- 🌸 Suitable for ponds, tub ponds, and low-tech aquariums, where it will readily flower
- 🐠 Very hardy against herbivorous fish and snails
- ⚓ Can be freely grown underwater mid-water or planted in the substrate
Planting and care tips
- Can be planted in plain sand or left to float freely in mid-water
- Easy to propagate by cuttings: cut a stem and replant it
- Likes light but also tolerates less brightly lit areas
- Highly oxygenates the water, often visible through its photosynthesis bubbles
- Regularly remove a few stems to prevent it from becoming too invasive
FAQ - Egeria najas in aquariums & ponds
What is its adult size?
Up to 60 cm, depending on the space and conditions. Some stems may grow longer but then break easily, forming two stems.
Can it be planted in sandy substrate?
Yes, it adapts perfectly to plain sand, since the substrate is only used to anchor it. It obtains all its nutrients from the water.
Does it flower?
Yes, its flowers are very similar to those of elodea: right at the surface, with a few crumpled ivory-white petals resembling tissue paper!
Can it live alongside goldfish?
Yes, even the hungriest herbivorous fish cannot finish off its hardy leaves! Goldfish prefer duckweed.
Is it suitable for outdoor winter conditions?
Yes, it withstands the cold but stops growing during the cold season. It resumes growth in spring, a little later than elodea.
