Echinodorus bolivianus ( Helanthium bolivianum )
Helanthium 'bolivianum’ from South America has characteristic light-green leaves 10cm long which form a good contrast to the darker aquarium plants. It is most beautiful when planted in groups, each roset becoming 10cm wide. In good conditions it produces runners which spread over the bottom. Very light leaves are a sign of a shortage of micro-nutrients.

Aquatic plants from tissue culture offer several benefits. They are free from pesticides and unwanted extraneous organisms such as parasites, pathogens, snails, planarians, insect larvae, algae and annoying "weeds" such as duckweed. The pesky removal of rock wool is omitted completely. And with one portion you get quite a large number of small individual plants.
