Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Azolla caroliniana (Carolina Azolla, Carolina Mosquito Fern, Water velvet) is a species of Azolla native to the Americas, in eastern North America from southern Ontario southward, and from the east coast west to Wisconsin and Texas, and in the Caribbean, and in Central and South America from southeastern Mexico (Chiapas) south to northern Argentina and Uruguay. It is a freshwater aquatic fern, with scale-like fronds 5–10 mm long, green to reddish, most often reddish in strong light and in winter. They are covered in fine hairs that give it the appearance of velvet. It is able to fix nitrogen from the air by means of symbiotic cyanobacteria. It can survive winter water temperatures of 5 °C, with optimum summer growth between 25-30 C.
