Proserpinaca is a stem plant, cultivated in closed cups and delivered with saw-toothed leaves, which
after a transitional period in the aquarium develop into long, finely denticulated, needle-like leaves.
In good light conditions it turns a beautiful copper colour and its characteristic appearance is a
pleasing contrast to other plants. It varies according to its origin. The Tropica cultivar is found on the
Isla de la Juventud of Cuba. In the USA the plant is commonly known as "mermaid weed".
