Helanthium bolivianum 'Quadricostatus'

Description from Tropica: Helanthium ‘Quadricostatus’ from South America has characteristic light green leaves 10-15 cm long which offer a great contrast to the 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. In good conditions, it produces runners which spread over the bottom. Very pale 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.    Type: Rosulate Origin: South America Growth Rate: High Height: 10-15+ cm Light Demand: Low CO2: Low   Plants are kept in tanks with fish and invertebrates. They are not snail free, but are duckweed free. If you would like snail free plants that are not kept with any livestock, we recommend ordering tissue cultures.
