A rhizomatous perennial herb of tidal mud-flats and saltmarshes, much planted as a mud-binder and forming extensive stands in many estuaries. It originated in Southampton Water (S. Hants.) in about 1890 as an amphidiploid derivative of S. x townsendii. Lowland.
The taxon was included within S. x townsendii in the 1962 Atlas, by which time it had become widespread both through deliberate planting and natural colonisation. It is not possible to separate native and planted populations and all are mapped as if they are native.
Endemic as a native to Britain, but widely planted in W. Europe.
