Helanthium 'Quadricostatus' from South America has characteristic light green leaves 10-15 cm long which offer a great contrast to other darker aquarium plants. It is most beautiful when planted in groups, each rosette becoming 15-20 cm wide. Thrives well even at a rather low light.
There is some confusion about the name of this plant, and it has been sold as Echinodorus bolivianus var. magdalenensis. It was also formerly called Echinodorus quadricostatus.
In good conditions, it produces runners which spread over the bottom. Very pale leaves are a sign of a shortage of micro-nutrients.
