Plant information
Dwarf Hairgrass
About this plant
Want a grass lawn underwater? Dwarf Hairgrass spreads by runner into a fine, meadow-like carpet — the classic foreground for Iwagumi and nature-style layouts, and the plant most people picture when they imagine a carpeted tank.
You may know it as Eleocharis parvula. That is the trade name — see the note below.
What you'll receive
- Bare-root Plants | small clump portion, bare-root plants
Why two scientific names?
Dwarf Hairgrass has been sold as Eleocharis parvula in the aquarium trade for a very long time, and most hobbyists still know it by that name.
Eleocharis parvula is a real species — but it is a brackish water plant, not suited to freshwater aquariums. Almost everything sold in the hobby under that label is in fact Eleocharis pusilla, a freshwater species.
So the plant you receive is Eleocharis pusilla: the same Dwarf Hairgrass you have always bought, correctly named, and genuinely suited to a freshwater tank.
- Pictures are not the actual plants you will receive, but a sample representation. Unless specific, we don't guarantee aquatic plants will be free of pests, and pesticides, grow emerged or submerge.
- Never release aquarium plants into natural waterways.

Grower's notes
- Split the clump into many small portions. Divide into groups of a few blades and plant them an inch apart. Runners only travel into open substrate, so a single lump takes months longer to fill a foreground than the same plant spread out.
- Keeping it alive is easy; carpeting it is not. That gap is why this is rated Intermediate. Survival needs little, but a dense low lawn needs strong light at substrate level and usually CO₂ — without both, expect a thin, stretched meadow.
- Light reaching the substrate is what decides carpet versus stretch. Shaded hairgrass grows long and thin instead of dense and low.
- Trim the carpet once established. Cutting it back encourages runner growth rather than height.
- Expect the emersed blades to melt back after planting. New growth comes from the runners, not the original blades.

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.

Typical online shops
Customers praised this aquatic grass for arriving "healthy and vibrant green" with excellent packaging. Most report strong growth and successful carpeting. While shoppers appreciate the quality, some noted small quantities and one mentioned high shipping costs. A few reviews cited fragility during planting.
- Beautiful grass. Arrived healthy and vibrant green.
- The quality was out of this world!
- Stunning and lush!!!
Beautiful grass. Arrived healthy and vibrant green. I highly recommend this shop. I will definitely be ordering from them again.
The packing was amazing, insulated packaging and plants were still moist when arrived. I bought the Dwarf Hairgrass on special so I may have received a little less I'm not too sure but the quality of it was amazing. I was a first time buy and will be a repeat buyer, the quality was out of this world!
3 miserable little pieces
Sure it should not cost more to be a little generous
Oh well they’ll grow
22 dollars a little much for shipping
They seem to be doing very well.
All plants came in looking great and are doing great
The bare rooted ferns were in great condition there were quite a few bare rooted plants in each packet and the grass had nice size bunches in each packet
Great!
Always receive plants in great shape. Got enough of a small clump to fill in my small shrimp.nano.
3/4 doing well
First time ever trying dwarf hairgrass why I couldn't tell you? Always went with sag or monte but I must say the pieces sent to me of this was incredible thank you! 5 ⭐'s ✨💯✨
Great quality as always
Adds a nice carpet to the bottom of my tank and starting to spread.
I received way more than expected and had lots of roots to help plant. Was a little shorter than hoped but already growing in my tank. Would buy again
Some broke apart easily
This dwarf hairgrass came in great condition, better than I've seen at my LFS!!! It is already starting to send runners.
Seriously I'm pretty sure my comment would get flagged out of how many f-bombs of wonderfulness I can give to this place they are absolutely the lumping greatest people that ever existed. My plans came in perfectly and I will include pictures later on unfortunately I am driving right now but this popped up and I just had to leave a review of how lumping great my experience was.
Everything was packaged perfectly it came even a day sooner than they said it would and for once I found a aquatic plants supplier that does what they say they will do God I love this lumping place
Plants arrived in excellent condition. Green, densely packed, and well packaged.
Great portion, but had alot of snails.
good quality and fast shipping
Return customer & always will be. Your products are fabulous & customer service is dynamic.
how much hair grass do you get for $6.99? i can’t find any info on this.
A small portion similar to the picture on the website.
How do you plant this so it stays anchored into the substrate while it gets established?
For Dwarf Hairgrass, bury the small root/rhizome section just under the substrate surface, leaving the green blades exposed above. Since it can float or get uprooted before it establishes, it helps to use small planting weights, plant it in slight depressions, or gently press the substrate around the base. Keeping flow moderate (not blasting the new plantings directly) for the first week or two also helps it root in before you increase circulation.
