🌱 What is Vallisneria?
Vallisneria is a genus of fast-growing aquatic plants with grass-like leaves. The plants are fully submerged (grow underwater) and spread via runners. Vallisneria is one of the oldest known aquarium plants and is known for its reliability and ease of care.
🌿 Popular Vallisneria Varieties
| Kind | Leaf shape | Height | Difficulty level |
|---|---|---|---|
| Vallisneria spiralis | Narrow, straight leaves | 30–60 cm | Easy |
| Vallisneria americana (gigantea) | Broad leaves, very long | 60–150 cm | Easy |
| Vallisneria asiatica | Slightly twisted leaf | 30–50 cm | Easy |
| Vallisneria spiralis red | Narrow, straight leaves | 30–60 cm | Easy |
| Vallisneria torta | Gracefully curled leaves | 30–60 cm | Easy |
💧 Care & Growth
- Light: Low to moderate – more light = faster growth
- Temperature: 20–28°C
- pH: 6.5–8.0
- CO₂: Not necessary
- Nutrition: Carrot tablets recommended
Vallisneria grows quickly, especially with good soil nutrition. CO₂ isn't required, but it can accelerate growth. Regular thinning prevents the plant from becoming too dominant.
🪴 Planting and Setting Out
- Do not plant too deep: leave the crown (where the root and leaf meet) above the substrate
- Use sand or fine gravel with root tablets
- Leave plenty of space between plants – they propagate quickly via runners
🎨 Aquascaping Applications
Vallisneria is ideal for:
- Background planting – creates a "curtain effect"
- Biotope aquariums (e.g. South America, Asia)
- Fish-friendly aquariums – provide hiding places
Note: Vallisneria can overshadow other plants, especially in smaller aquariums.
❓ Frequently Asked Questions
My Vallisneria is melting, what now?
This is often transplant shock. Leave the roots alone – the plant will usually recover on its own after a few weeks.
How does Vallisneria spread?
Via runners (cuttings) that spread horizontally under the substrate.
Can you prune Vallisneria?
Yes, cut the leaves off at the base or top if they get too long. Prune carefully to avoid damaging the growing point.
✅ Conclusion
Vallisneria is a reliable, fast-growing background plant that requires little effort. Its easy care and decorative appearance make it an excellent choice for any freshwater aquarium—from beginner to expert. Don't forget to prune regularly and manage suckers!
