Atriplex paludosa, commonly known as marsh saltbush, is a species of saltbush endemic to Australia
Marsh Saltbush Atriplex paludosa subsp. paludosa is a sprawling shrub, growing to 1.6 metres tall. The leaves are green and smooth on the upper surface and densely mealy and whitish below, growing up to 40 mm long x 8 mm wide. It is mainly dioecious with male flowers in dense clusters (photo) and female flowers few in upper leaf axils or terminal spikes to 15 cm long. Flowers and fruit occur at most times of year. There are four subspecies of Atriplex paludosa but only one found in Victoria. Although locally common along the fringe of the coastal saltmarsh on Anderson Inlet, Marsh Saltbush is classed as rare in Victoria. It is also found from Western Australia to New South Wales. Marsh Saltbush grows in full sun, is fire-resistant, drought and salt tolerant and excellent for soil erosion control. Aboriginal people ground and cooked the seed. Propagation is from seed or cuttings. Atriplex belongs in the Chenopodiaceae or Saltbush family and the genus name comes from the Latin Atriplexum, meaning saltbush. The species name paludosa means ‘of the swamps’.
