Hygrophila pinnatifida is one of the most highly prized hygros currently in the aquarium hobby. This versatile plant is perfectly at home growing in the substrate, but what really makes it stand out among stem plants is its ability to grow epiphytically! If glued, tied, or simply wedged into a piece of rock, wood, decor, etc, this plant will affix itself over time and begin creeping along, just like an Anubias or Java Fern.
