Plant information
Littorella Uniflora
About this plant
A grass carpet that also grows out of water. Littorella uniflora — American Shoreweed — forms low, dense clusters of narrow bright green leaves and spreads by runners, thriving equally emersed or submerged. That amphibious range is the reason to choose it: it works in an aquarium foreground, a riparium margin or a pond shoreline without changing plants.
What you'll receive
Fresh, healthy Littorella uniflora cultivated and prepared by Aquarium Plants Factory®, available in multiple growth forms and pack sizes:
- Bare-root Plants — individual plants with exposed roots, ideal for planting directly into substrate
- Rooted Bunched — multiple rooted plants bundled together with foam and a plant weight for easy placement
- Rooted Potted — fully rooted plants grown in rockwool and secured in a net pot for maximum stability
1 Pack — ideal for small tanks or accent planting
5 Pack — great for foreground coverage
10 Pack — best for larger aquariums or dense planting layouts
Plant quantity per pack may vary slightly based on size and growth form.
- Submerged growth may differ in appearance from emersed growth as the plant adapts to underwater conditions. Temporary melting or leaf adjustment can occur during transition and is normal.
- Never release aquarium plants into natural waterways.

Grower's notes
- It wants cooler water than most carpets. At 65–75°F it is comfortable; pushed into the low 80s alongside tropical fish it slows and thins. This is the plant to pick for an unheated or lightly heated tank, and the wrong one for a warm discus setup.
- Separate into small portions and plant them an inch apart. Runners only travel into open substrate, so spacing decides how quickly it closes.
- Feed at the roots. Runner production stalls without a nutrient substrate or root tabs.
- Emersed and submerged growth look different — shorter and stiffer out of water, longer and softer under it. A change in leaf form after planting is the plant converting, not failing.
- Compare with Micro Sword, which carpets similarly but takes tropical temperatures.
How it arrives
A sealed Vitro Culture® bag
Lab-grown plantlets in nutrient gel, free of snails, algae and pests.
- Keep it sealed at room temperature, out of direct sun, until you're ready to plant.
- Rinse off all the gel under lukewarm water. Left in the tank, it clouds the water and feeds algae.
- Split into small portions and plant with tweezers. Small portions spread faster than one big clump.
Normal: a little melt in the first weeks as underwater leaves replace the leaves grown in the lab.
Rooted plants in a net pot with rockwool
The most stable option, with roots already established.
- Rinse the plant under clean water.
- Plant the pot as is, or ease the plant out and gently tease away the rockwool. Either way works.
- For epiphytes like Anubias and Bucephalandra, keep the rhizome above the substrate or tie it to wood or rock.
Fresh-cut stems in a net pot with rockwool
Freshly cut stems without roots, held upright in a net pot for a quick setup.
- Rinse the stems under clean water.
- Plant the pot as is, or remove the stems and plant them one by one, an inch or two deep.
- New roots usually form within a couple of weeks.
Rooted plants bundled with foam and a plant weight
Easy placement plus the stability of roots.
- Rinse the bunch under clean water.
- Place the bunch as is, or remove the foam and weight and plant each one separately.
- Give each plant room so light reaches the lower leaves.
Fresh-cut stems bundled with foam and a plant weight
Freshly cut stems without roots, ready to drop in.
- Rinse the stems under clean water.
- Remove the foam and weight and plant stems one by one, an inch or two deep, for the fullest look. You can also place the bunch as is.
- New roots usually form within a couple of weeks.
Loose, rooted plants
No pot or foam, so you can place them exactly where you want.
- Rinse the plants under clean water.
- Plant the roots into the substrate.
- Trim any broken leaves; new growth follows once settled.
Loose, fresh-cut stems
Freshly cut stems without roots, for full flexibility.
- Rinse the stems under clean water.
- Plant stems one by one, an inch or two deep, with a little space between them.
- New roots usually form within a couple of weeks.
A bulb, ready to sprout
Bulbs ship either dormant or already sprouted with leaves, depending on the option you choose.
- Rinse the bulb under clean water.
- Rest it on the substrate or press the base in slightly. Don't bury the top.
- A dormant bulb can take a few weeks to send up its first leaves.
A young sprouted tuber
Ready to pot up and grow into a full plant.
- Pot it in a wide container of heavy garden soil, crown just above the soil.
- Start shallow and lower it deeper as the leaves grow.
- Give it full sun once the leaves reach the surface.
Attached to hardscape
Already growing on rock or wood, so it's ready to place.
- Rinse the piece under clean water.
- Place it anywhere in your layout. No planting needed.
- Keep the rhizome out of the substrate.
Packed fresh to travel well
- Open the box as soon as it arrives.
- Rinse the plants under clean water.
- Plant or place them the same day if you can.

Are your plants free from pests, algae, and pesticides?
Our plants are very clean, but we can’t guarantee they will be 100% free of hitchhikers (snails, algae, pests), because we can’t be responsible for your aquarium. We recommend rinsing all plants with clean water and quarantining them before use.
Plants in our Tissue Culture collection are 100% free of pests and algae and have never been in contact with any aquarium.
We don’t guarantee our plants are free of pesticides. We use homemade, organic pesticides in our greenhouse to control pests, and never pesticides containing copper, which is toxic to invertebrates such as snails, crabs, and shrimp.
We don’t guarantee your aquarium’s success and aren’t responsible for its inhabitants, including but not limited to fish, shrimp, snails, and turtles. Please quarantine all plants before use!
Are your plants grown emersed or submerged?
It depends on the species. Most of our plants are grown hydroponically in a controlled-environment greenhouse.
Common stem plants such as Ludwigia, Bacopa, and Myriophyllum, and rheophyte/epiphyte plants (Anubias, Bucephalandra, Microsorum, Bolbitis, etc.) are grown emersed, hydroponically, in a controlled high-humidity environment.
True aquatic plants that can’t grow emersed — such as Vallisneria, Elodea, Najas, Cabomba, Potamogeton gayi, and Ceratophyllum demersum — are always cultivated submerged, underwater.
Should I remove the foam, weight, or pot before planting?
It’s totally up to you — we usually keep them as they are!
What’s the difference between fresh-cut, bare-root, and potted plants?
All options offer the same high quality; they differ in how they are prepared and packaged:
- Fresh-cut Plants: loose, freshly cut plants without roots. Great flexibility if you prefer to plant them your own way.
- Fresh-cut Bunched: freshly cut plants without roots, bundled with foam and a plant weight, ready to place in your aquarium.
- Fresh-cut Potted: freshly cut plants without roots, potted in a net pot with rockwool for stability and a quick setup.
- Bare-root Plants: loose, rooted plants you can position exactly where you want.
- Rooted Bunched: rooted plants bundled with foam and a plant weight — easy placement plus the stability of roots.
- Rooted Potted: rooted plants potted in a net pot with rockwool — maximum stability and a low-maintenance setup.
Choose based on your planting preference and your aquarium setup.
