Ferns
Medium care
A fully aquatic fern forming rosettes of tender, bright green fronds. The floating barren leaves develop young plantlets along their margins, making it a naturally multiplying species. Fertile fronds are finely divided into narrow linear lobes. Popular in Asia as a leafy vegetable and widely used in aquascaping and shallow aquatic gardens.
