[Wikipedia] Western Australia native, Description: Atriplex amnicola, commonly known as river saltbush or swamp saltbush, is a species of shrub in the family Amaranthaceae. Endemic to Western Australia, it is native to the floodplains of the Murchison and Gascoyne Rivers. River saltbush is very highly salt tolerant, and is used in Australia in the rehabilitation of saline areas. When grown in saline soil, it has the best long-term survival and growth of any saltbush. It is also fairly drought tolerant, and tolerates waterlogging well once mature. It is highly favoured by sheep, and recovers well from grazing. Studies have shown that the meat of sheep grazed on river saltbush is high in Vitamin E and has high "consumer appeal". Disadvantages include a low volunteering rate, and difficulties establishing by direct seeding. (link added by Mary Ann Machi)
