Common Names

Carolina Mosquito Fern, Water Velvet are common names of Azolla caroliniana.

Origin

This plant species is widespread over North America right down to Central America.

Planting Area

Never attempt to plant this plant in the substrate as it’s a floating species.

Lighting Requirements

Bright lighting will speed up the growth of this plant, however it can tolerate medium lighting with no ill effect (proper ratio of nutriments must be present in the water, otherwise bright lighting is of no use anyway).

Propagation

Azolla caroliniana will be propagating itself by runners which are sent out. A young plant will be on the end of these runners. These are often two leaf juvenile plants and as they grow in size and develop more leaves they will detach themselves from the parent plant.

Difficulty

Easy if given the correct requirements.

Short Description

Azolla caroliniana is cultivated as a fertiliser as it has an ability to store large amounts of nitrogen from the water; this makes it very popular in the aquariums as the addition of these will reduce the nitrate levels in the tank. It is also used for fish food and poultry food production.
