About
Ceratopteris thalictroides is a fern species belonging to the genus Ceratopteris, one of only two genera of the subfamily Parkerioideae of the family Pteridaceae.
How to grow it
It grows best in soil with a pH reading of 5-9 and in very high amounts of light. It usually grows quickly.
C. thalictroides can benefit (like all aquatic plants) from the addition of CO2. The plant's reproductive technique is similar to other ferns. Small adventitious plantlets are grown on the mother plant and are then released when ready.
Where it grows
Ceratopteris thalictroides is widespread across the tropical and subtropical regions of the world, occurring as far north as Korea and as far south as western Australia.
