Atriplex suberecta is a species of saltbush known by the common names sprawling saltbush, lagoon saltbush and (in Britain and Ireland) Australian orache. It is native to Australia.
It can be found on other continents as an introduced species and invasive species, including southern Africa and parts of North America. It is sometimes considered a noxious weed.
This is an annual herb producing sprawling, scaly stems 20 to 60 centimeters long. The thin, toothed leaves are oval to diamond-shaped and up to 3 centimeters long. The male and female flowers are generally borne in axillary clusters.
