Propagating Hygrophila Polysperma is more of a necessity than a choice as new lateral
shoots are constantly forming on its stems. This combined with its fast growth rate.
Propagation is achieved by simply cutting off the top of the stem or lateral shoot
and replanting it in the substrate, roots are formed very soon and the plant will
begin to grow. The reproductive easy of Hygrophila Polysperma has made it one of
the cheapest and readily available plants, both in pet stores and online.
Noxious weed status
Hygrophila Polysperma is a state-listed noxious weed in Florida by the Florida Department
of Environmental Protection. Florida has a very suitable climate for Hygrophila Polysperma
and as a result it is listed. In Florida it may still be cultured but neither imported
nor collected from the wild. It’s hardiness and speed of growth both contribute to
its ability to compete with other native species. It mustn’t be released or discarded
into any wild waterways.
Hygrophila Polysperma generally tends to grow in moving water although it can be
grown in lakes and ponds, often caused by the plant being released into wild waterways.
Hygrophila Polysperma originated in India. Polysperma can easily invade and cut off
light to other plant species, owing to its fast growth and easy of propagation. It
grows adventitious roots meaning that small parts of the stem can quickly begin to
grow new Hygrophila plants in very little time. Whist preferring warmer waters, Hygrophila
Polysperma is remarkably tolerant of both temperature and water parameters.
