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. Hygrophila 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 CO 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.
