Common: Wright’s Saltbush
Arizona, New Mexico, and Texas
Annual Saltbush flowers summer into early fall. It is found in alkaline or saline habitats, often along roadsides, in undisturbed fields, and in vacant lots. It is an annual with erect stems and grows to be 8-40 inches tall. The leaves are green on top and silvery on the bottom with a weakly wavy edge. Annual Saltbush sheds copious amounts of spheroid pollen grains in the summer through fall. Annual Saltbush pollen is highly cross-reactive with other species in the genus Atriplex, such as four-wing saltbush, shadscale, and lenscale. Atriplex species are also cross-reactive with pigweed and Russian thistle.
