[edit] Remarks
Very persistent but perhaps slow spreading where introduced in streams. Does well in quiet streams and shallow water.
Edible: available commercially, outside of cultivation take care to avoid polluted water---if you would not drink the water, don't eat the watercress. Chlorinate and wash prior to eating.
