The Proserpinaca Palustris, or commonly known as the Mermaid Weed is known as one of the most beautiful freshwater plants due to its bright coloring and intricate leaves. It is an easy plant to grown but is a slow grower. In good light with supplemental CO2 it can achieve a lovely hue. The slow growth makes it a good choice for smaller tanks. When planting make sure it is not crowded so light can reach the bottom of the plant.
