About Pondweed (Stuckenia pectinata) Potamogeton pectinatus, called fennel pondweed (UK) or sago pondweed (US), is a cosmopolitan water plant species that grows in fresh and brackish water on all continents except Antarctica. It is fully submerged and does not have any floating or emerged leaves. The flowers are wind pollinated and the seeds float. Tubers that are rich in starch, are formed on the rhizomes.
