Hygrophila polysperma

The original form is a native of India and now widely distributed in Asia. A very hardy and adaptable species. The lanceolate green submersed leaves often acquire a brown hue under Strong light. They are 2.5CM to 5 CM long and  1CM to 1.5CM broad. A few plants in the aquarium tank will soon become bushy with the growth of lateral stems. This plant should be pruned regularly, otherwise, it will form a dense growth across the water surface and deprive other plants of light. The leaf size is variable, hence, many varieties such as Hygrophila polysperma broad leaf and Hygrophila polysperma narrow leaf are now common in the aquarium plant trade. An ideal background plant which can create a green curtain across the back of the tank.
