Widespread in drier inland parts of Victoria where it favours disturbed areas, especially on heavy soils near waterways or seasonally inundated sites.

Intergrades, possibly hybridizes, somewhat with H. heterophylla and H. glauca.

Common on agricultural land where it is a troublesome weed due to its deep stoloniferous rootstock.
