Atriplex argentea is a species of saltbush known by the common names silverscale saltbush and silver orache. It is native to western North America from southern Canada to northern Mexico, where it grows in many types of habitat, generally on saline soils.
Atriplex argentea is an annual herb producing branching stems which spread out low to the ground or reach erect to maximum heights approaching 80 centimeters. The leaves are triangular to roughly oval in shape and 1 to 4 centimeters long. The stems and leaves are coated in gray scales.
