Townsend's cordgrass (Spartina x townsendii) is a hybrid that originated in northern Europe (i.e. southern England and western France). It is thought that this hybrid came about when smooth cordgrass (Spartina alterniflora) was introduced to Great Britain from North America in ship ballast water. This introduced species is thought to have crossed with the native small cordgrass (Spartina maritima), resulting in the appearance of the sterile hybrid known as Townsend's cordgrass (Spartina x townsendii).
Locally naturalised in some coastal districts of south-eastern Australia (i.e. in Victoria and south-eastern South Australia).
Also naturalised in western Europe, north-western USA (i.e. Washington) and New Zealand.
Townsend's cordgrass (Spartina x townsendii) is regarded as significant environmental weed in Victoria, and is listed as a priority environmental weed in at least one Natural Resource Management region in this state.
