The Dwarf Hygrophila is a really popular plant among aquascapers. Its not slow growing aquarium plants such as Staurogyne Porto Velho. It is extremely fast growing with good light and CO2 injection. Therefore Hygrophila polysperma needs to be pruned regularly to maintain its health. The growth of this species is often so rapid that a trim of some sort is required within two or three weeks of the last pruning. It reproduces from both cuttings and side shoots. The cuttings can even be as small as a single leaf in nutrient-rich environments.

It's really easy to grow and it will multiply just by putting the clippings back into the gravel, even a free floating leaf of this plant will make an entire new plant!
It has proven to be a true survivor - Hygrophila polysperma survived and thrived for 6 weeks without adaquate light, filtration, CO2, or fertilization. A truly difficult aquarium plants to kill, and a lovely addition to the planted aquarium.
