Description
Overview: Java Fern is perhaps the most famous aquarium plant in the world. Its ability to grow in almost any conditions—very low light, no CO2, and a variety of water parameters—makes it the ultimate beginner plant. It features tough, leathery green leaves. It reproduces easily by growing "adventitious" plantlets on the tips of its leaves. It is a staple for any tank where easy maintenance is the priority.
