TL;DR, Vallisneria Spiralis
Carpets the back of a tank in long, curving ribbons. Sensitive to liquid carbon (Excel/Easy Carbo), will melt. Snip runners to control spread.
Vallisneria Spiralis (Vallisneria spiralis) is a rosette / runner aquatic plant for the background of a planted tank. It reaches 30–60 cm under good conditions and grows at a fast rate. Light: low to medium. CO₂: none to optional. Target 18–28 °C, pH 6.5–8.0, and 5–25 dGH. Substrate: Sand or gravel with root tabs. Propagate via runners.

Who it lives with
Tank-mate safety and the species this one is documented to thrive (or fail) alongside.
Pro tips
Hard-won lessons from the tank.
Plant runners deep enough to anchor but with crown above substrate. New tank? Vallisneria will melt completely before recovering — don't dig it up. It comes back from the root mass in 4–8 weeks. CANNOT TOLERATE LIQUID CARBON — this is the most common Val killer.

Things to watch for
Failure modes, in order of how dramatic the fix is.
Nutrition
Common deficiencies
Yellow leaves: iron. Brown tips: too much excel/glutaraldehyde (this kills Vallisneria — never dose liquid carbon).
Algae
Algae issues
Algae rarely an issue once established. New planting can suffer melt from transition stress.
How to care for it
The practical routine, read top to bottom.
Fertilization
Moderate root feeder. Root tabs every 4 months. Iron in water column for green leaves.
Trimming
DON'T trim by cutting tips — leaves will die back further from cut. Instead remove entire damaged leaves at the base. To control spread, snap runners.

Where it lived before it came home.
Origin · Europe, Asia, Africa
Worldwide warm temperate to tropical freshwater. Slow rivers, lakes, ponds.
Emersed form
Does not grow emersed naturally — fully aquatic. Leaves can persist briefly out of water but plant dies.
Flowering
Female plants send up a spiral stalk that emerges at the surface to flower (the 'spiral' in spiralis). Male plants release pollen-carrying free-floating flowers. Rarely flowers in aquariums.
Variants & identification
The named cultivars and the lookalikes worth flagging.
Variants / cultivars
V. spiralis (small, ribbon-like, often called 'Jungle Val' if larger), V. asiatica, V. nana (true dwarf), V. americana (large), V. spiralis 'Tiger' (striped).
Misidentification
Often confused with Sagittaria (which has spear-shaped leaves) and Sagittaria subulata 'Jungle Val' (a misnomer — that's actually Sagittaria).
Frequently asked questions
Direct answers to the questions search engines and AI assistants surface most often about this species.
Does Vallisneria Spiralis need CO₂?
CO₂ requirement: none to optional. Light requirement: low to medium. Under low-tech conditions the plant grows at a fast rate.
What light level does Vallisneria Spiralis need?
Vallisneria Spiralis (Vallisneria spiralis) needs low to medium light. Run a photoperiod of 6–8 hours; longer photoperiods invite algae unless CO₂ and dosing are dialled in.
Where should Vallisneria Spiralis be planted?
Position: background. Substrate: Sand or gravel with root tabs It typically reaches 30–60 cm.
How do you propagate Vallisneria Spiralis?
Propagation method: Runners. Vallisneria Spiralis is a rosette / runner plant.
What water parameters does Vallisneria Spiralis tolerate?
Target 18–28 °C, pH 6.5–8.0, and 5–25 dGH. Flow tolerance: medium to high.
Is Vallisneria Spiralis suitable for beginners?
Difficulty: 1/5. Almost unkillable, a solid first-tank choice.
