Leave it alone. It is very rare for an Echinodorus grown submersed to flower, but adventitious plants will be produced from the nodes along the stem. Echinodorus will flower if grown emersed as a bog or marsh plant. If you read the plant's profile this is all explained. Click on the shaded name, Echinodorus bleherae.
