Helanthium 'Quadricostatus'

Helanthium ‘Quadricostatus’ from South America has characteristic light-green leaves 10-15 cm long which form a good contrast to the darker aquarium plants. It is most beautiful when planted in groups, each roset becoming 15-20 cm wide. In good conditions it produces runners which spread over the bottom. Very light leaves are a sign of a shortage of micro-nutrients. There is some confusion about the name of this plant, and it has been sold as Echinodorus bolivianus var. magdalenensis.
