Rotala Nanjenshan is also known as Green wallichii. It is an ideal background plant that will add color to the freshwater planted aquarium. Because of the small leaf size, it will grow rather densely, and may need to be thinned out in time. It requires high light and CO2 to grow better. Final coloration is ultimately dependent upon the conditions this plant is kept in. Stem cuttings can be used for propagation.
