🍃 Azolla (Fairy Moss) – Floating Water Fern for Natural Filtration & Shade
Azolla caroliniana, commonly known as Fairy Moss, Water Fern, Mosquito Fern, Duckweed Fern, or Water Moss, is a fast-growing, floating aquatic fern that adds natural beauty and ecological function to ponds, aquariums, and outdoor water features. Its tiny, overlapping leaves form a delicate mat on the water’s surface, creating a soft, textured blanket of green that turns red or bronze under strong sunlight or cool temperatures.
Known for its ability to absorb excess nutrients, shade the water surface, and inhibit algae growth, Azolla is a favorite among aquarists and pond keepers for its low maintenance and high impact. It also provides excellent cover for shrimp, small fish, and tadpoles, while helping to reduce mosquito breeding.

📦 What You’ll Receive:
Our Azolla is sold by portion size and packed in resealable bags. The dimensions below refer to the approximate bag size, not the coverage area after the plants are released into your aquarium or pond.
| Portion Size | Approx. Bag Size | Suggested Count | Notes |

Please Note:
- Plant counts are approximate since Azolla plants naturally vary in size.
- Azolla is extremely small and reproduces rapidly under suitable growing conditions, so the number of plants will increase over time.

Azolla grows rapidly and may require regular thinning in well-lit or nutrient-rich environments. Not recommended for tanks with strong surface agitation or high flow. May be restricted in some regions—please check local regulations before purchasing.

Please keep in mind that Live Arrival Guarantee only guarantees that live stocks will be alive upon arrival. We cannot guarantee that you will continue to have success with them. Many factors, including the aquarium environment, water quality, nutrient, temperature, lighting, filter, and CO2 system, can contribute to the failure to grow live plants and live animals.
WHAT WE CAN'T GUARANTEE
Even though our plants are very clean, but we can't guarantee they will be 100% pest-free because we cannot be responsible for your aquarium. Please use it at your own risk. We recommended all customers rinse the plants with clean water and quarantine them before use.
However, plants in tissue culture will be 100% free from pests, algae and never have been contacting with any aquarium.
- Due to the nature of the product. We don't guarantee our plants will be pests free. ( snails, algae, hitchhikers )
- We don't guarantee our plants will be free of pesticides. We use homemade, organic pesticides in our greenhouse to control pests. We do not use pesticides that contain copper. Copper is toxic to invertebrates such as aquatic snails, crabs, shrimps, etc
- We don't guarantee your aquarium success or are responsible for your aquarium inhabitant including but not limited to fish, shrimp, snail, turtle, etc. So please quarantine all plants when use!
- Unless specific, we don't guarantee aquatic plants will be grow emerged or submerge.
Please review your state's regulations on restricted plants, as we are committed to not shipping plants that are restricted in your area. Do not release any plants into the wild or waterways, as this can harm local ecosystems by introducing invasive species.
Your cooperation in protecting the environment is appreciated. For continuously updated information, refer to the USDA State Noxious Weed list here.

Customers praised this floating aquatic plant for arriving healthy with "expertly packaged" delivery. The moss multiplies well and adds color to water gardens and tanks. Shoppers loved the "leaf pattern and dangling roots." Some noted it's tiny and harder to see detail than expected, grows slower than duckweed, and portion sizes vary. Overall highly recommended for tanks and ponds.
- Arrived healthy and has since multiplied.
- The plants were expertly packaged and arrived healthy.
- Love this moss! I love the leaf pattern and how the roots dangle down.

Love this moss! I love the leaf pattern and how the roots dangle down.

Amazing plant. Arrived looking good except the roots had died off and they were a little annoying to separate from the leaf part before putting in the tank but it loves it. I was a little sceptical about buying this plant as I have heard many stories of it just shriveling up and dying but I am so glad I did. As soon as it was in the tank it took off lots of new growth and the roots were back in 2 days.
Final statement - Happy Happy Happy.

Arrived healthy and has since multiplied.

The plants were expertly packaged and arrived healthy. I purchased them for my water garden.

I made 2 purchases separately for azolla I think I didn't do a review for the 1st. They were both perfectly good healthy plants I just needed more.
The first batch I didn't have compost tea on hand to help them along & we had a sudden re-frosting in OH that I wasn't expecting & didn't have time to bring them indoors. They seemed to survive with a little browning on their edges, but then some tree cutters doing work for my neighbor (they had just finished up working in my backyard I gave the neighbor their info) dumped the pool of water containing my azollas (I guess they thought it was in their way?) to back their truck up to the tree on my lot being worked on.
This, of course, prompted the 2nd purchase. Can't wait to see them spread I'm testing this plant out for future poultry feeding purposes. The team provided them swiftly, alive, & healthy I have no complaints.

I created a balcony pond ant the fairy moss was shipped quickly in secure packaging, was very easy to drop into the water. added a nice pop of color

I ordered this as an experiment to see how it does in my moss only tank which contains a strong colony of shrimp. I have just about every common floater plant out there and never heard of this before. Product arrived alive and well, but I wish the portion size was slightly larger. A small covered about a 3x3 inch surface area of my tank.
I am finding that this is just as messy as duckweed, but grows significantly slower and after one week appears less hardy. Hindsight I probably would not order it again, but 5 stars because I got what I ordered and was fun to try.

It was my first time ordering from Aquatic Plants Factory, so I wasn't sure how much I would get from a "small portion" but after receiving my order in the mail one small portion is way more than I expected. It was a small pouch that was just about completely full. They're a tiny floating plant, so it was awesome to get so many at once! It's also important that they survived the shipping process. I would buy this again!
T
The moss is pretty much as pictured, healthy etc. BUT the scale is hard to determine from the pics. It's really pretty but the beautiful texture is quite hard to see unless you're sticking your face right up on it. In any case, I'm sure it'll do it's plant job of filtering etc, so it's going in the tanks.
A
Super clean and healthy plants. Typical duckweed and snails in but minimal. This was my second order if that says how I feel about it. Would recommend
W
Will this grow in a glass hanging orb in a northern window? I’m looking for a plant (suggestions)that will not get big. I can put a small drift wood in the bottom if needed
Azolla (Fairy Moss) is a floating plant, so it does not require driftwood or substrate. It will naturally float on the water surface. For a glass hanging orb, it can grow as long as there’s a small amount of standing water and it receives bright, indirect light.
