Mosquito Fern – Azolla

Mosquito fern gets its name from the belief that mosquitoes cannot lay their eggs in still water covered by this plant. Azolla is a tropical and sub-tropical water plant that resembles moss more than ferns. It has a symbiotic relationship with blue-green algae and grows well and quickly on the surface of still or sluggish waters. You are most likely to see it on the surface of ponds, but slow-moving streams may also be a good setting for mosquito ferns.
Mosquito Fern starts off small at barely ¼ inch in diameter, it can double its size in a matter of days. For this reason, it is known as a quite hardy and dense matting plant.
Mosquito Fern’s floating nature gives any enclosure a versatile and dynamic look. This article will provide a complete guide to the plant’s care and essential details.
