Italian Val
Scientific Name: Vallisneria spiralis
Common Names: Vallisneria, Italian Vallisneria, Vallisneria Spiralis
The Italian Vallisneria is a popular and widely recognized blackwater, biotope, and botanical method aquarium plant known for its rapid growth and ease of care. It is suitable for aquarists of all skill levels. It has band-shaped leaves and dense green stands, quickly growing into a dense carpet on the substrate, thus providing a lush green backdrop. This plant requires minimal maintenance and is often chosen by beginners as their first aquatic plant. Regular trimming may be necessary to prevent it from overtaking the ecosystem.
For optimal growth, the Italian Val requires sufficient lighting and the presence of trace elements in the water, which may necessitate occasional fertilizer supplementation.

contrast the tint with greenery
While the aesthetic appeal of tinted waters can be quite attractive to us, the recreation of nature—which includes both submerged and emersed plants—is the end goal. Flora helps to improve water conditions, feeding patterns, spawning displays, and territory building.

DOA Policy
Please ensure that you add a heat pack or cold pack to your orders if temperatures in your area are above 90°F or below 40°F. Click for more info on our DOA Policy.
Are these plants duckweed and snail free?
All Plants may contain snails or snail eggs, small macroinvertebrates, and duckweed. We keep them in all of our tanks for the benefits they provide. We have experienced the presence of small snails, ostracods, daphnia, and beneficial detritus worms.
Are your plants only for tinted water conditions?
Nope! All of our plants will grow perfectly in untinted aquariums that have CO2 and aquasoils, or low-tech planted aquariums. Our selection, though, is optimized for emersed plant growth and low- to medium-tinted water environments.
What is your aquatic plant shipping schedule?
We’re a small company and ship Tuesdays & Thursdays only. Orders placed Wednesday–Sunday → Ship Tuesday. Orders placed Monday–Tuesday → Ship Thursday
Are your plants just for bettas?
Nope. Our aquatic plants are safe for almost all aquariums, terrariums, vivariums, and paludariums. Many of our plants can be grown emersed in filter compartments, vivariums, or incorporated into wabikua.
What are Tannins?
Tannins are natural compounds released by leaves, seed pods, and bark as they decompose in water. They soften water, gently lower pH, and create the characteristic tea-stained tint found in blackwater habitats. But their role goes far beyond color—tannins fuel beneficial bacteria, fungi, and biofilms, which form the foundation of a healthy ecosystem. They also offer mild antifungal benefits and help reduce stress in fish by replicating the natural conditions they’ve evolved in. At their core, tannins are plant-derived antioxidants that connect your aquarium to the same processes at work in wild flooded forests and streams.
