Although this is a rhizome plant, division of the rhizome is not the only way this plant can be propagated. They will also develop adventitious plants around the mother plant. To propagate these it is simply a matter of prying them free from the rosette of leaves and re-planting them in the substrate. Ensure that they get nutrients added straight away to encourage the new root growth.
This plant was formerly sold as Echinodorus radicans and is one of the larger sword plants available to buy. It is best to house these in an open top aquarium as the leaves will extend above the water surface and even flower stalks may be produced if the conditions are correct. It is best to spray any leaves that are out of the water to prevent them from drying out.
