Hygrophila polysperma is a amphibious plant from the Indo-Malayan region. The aquatic form has an up to 50 cm long stem with opposed leaves very variable in shape and colour. The leaves of the emergent plants are narrower and dark green. It forms bright green tufts which grow towards the surface with good light. H polysperma has no particular demands as to bottom, being very sturdy and adaptive. Sand with a little mud and clay added is sufficient for 2-3 years of good growth when left alone, and the growth always benefits from CO2 enrichment of the water. Therefore it does not have a great tolerance for plants that have needs for alkaline water. Hygrophila polysperma is one of the easiest plants to propagate - all parts of the plant is able to root and form a new plant. Even a free-floating leaf will eventually form a new plant.
These plant are recognised as some of the most beautiful and robust aquarium plant on the market.
