Azolla Plant

Azolla is a floating fern with fronds that range from green to deep red. It tends to be greener when shaded and redder when in sunlight with high nitrogen water. Depending on the amount of sun and the nutrients in your pond it may take on a solid colour or grow with a rainbow effect as shown in the photograph.

Given ideal conditions Azolla's growth is prolific doubling its mass regularly. However because of Azolla’s small size it does not choke the water surface as thickly as noxious floating weeds such as salvinia.

Azolla’s growth inhibits algae by robbing the algae of light and nutrients. Scoop out excess Azolla for use as nitrogen rich plant mulch.

Azolla tends to survive winter more readily than duckweed and does not die back in tropical areas.

Azolla is generally less readily eaten by fish than duckweed and may be useful where fish tend to eat most pond plants.

You can also have success with azolla in the aquarium when provided with strong light.

Due to the varied nature of azolla’s colour, your plants may vary from the photograph. You will generally be sold several hundred plants in an average sized portion.

Azolla is seasonal and may not always be available. If no azolla plants are currently on offer please check back later or browse aquarium plants now available.
