River saltbush is a multi-branched shrub whose form ranges from prostrate to erect.

The branches of river saltbush spread along the ground, and may layer and take root, especially in the prostrate form.

This is a predominantly dioecious species, with male and female flowers produced on separate individuals.

River saltbush is very highly salt tolerant, and is used in Australia in the rehabilitation of saline areas.

Disadvantages include a low volunteering rate, and difficulties establishing by direct seeding.
