Description

Hygrophila polysperma 'Rosanervig' is as undemanding as standard H. polysperma, getting 20-40 cm tall and 5-8 cm wide. It is also known under the trade names 'Sunset' and 'Marmor' (i.e. Marble) and has a striking variegation with light nerves. But if you want deep-pink leaves you must provide intensive light. Otherwise the nerves are rather white.

The distinctive light colouring of the leaf nerves is probably caused by a virus which prevents chlorophyll from being produced in the cells around the leaf ribs, making them white. However, this virus does not affect other plants in the aquarium.

Hydrophila polysperma "Sunset", in Europe sold under the name "Rosanervig", has its origins in the Danish aquatic plant nursery Tropica. One special characteristic of this variety are the white-coloured leaf veins. They are not the symptom of a nutrient deficiency, though. It is assumed that a virus prevents the tissue around the veins from producing chlorophyll. This virus specialises in this variety only and thus poses no danger at all for the rest of the aquarium plants. This variety of the so well-known robust Asian H. polysperma has become a very highly coveted aquarium plant.

This undemanding red-coloured plant is very interesting as it is probably the easiest plant of that hue in cultivation. It grows under almost any conditions. (read more)

In the hot summer weather, it struggled at first and lost a lot of leaves. However, it is perfect now and the pink leaves at the top look really nice. (read more)
