C-Fern
Quick Summary
The term "C-Fern" is a trade name for a genus of aquatic ferns known as Ceratopteris. These ferns are small and float on the surface of still or slow-moving fresh water, though they can also root in mud. They are found in tropical and warm temperate regions worldwide and are sometimes cultivated as aquarium plants.12
Ceratopteris species are notable for their rapid life cycle, making them valuable tools for genetic research and education. They are also known for their ability to reproduce asexually, creating "daughter plants" that are essentially clones of the parent. The trade name C-Fern is used for various strains of these ferns, often with specific genetic mutations, which are made available to researchers and educators.1
