Gardner's Saltbush

Atriplex gardneri is a species of flowering plant in the amaranth family known by the common name Gardner's saltbush. It is native to western North America from British Columbia to Saskatchewan in Canada south to Nevada and New Mexico in the United States. The specific epithet of the species, gardneri, is misnamed after its first collector, Alexander Gordon. The naturalist Alfred Moquin-Tandon was under the impression that Gordon's last name was Gardner.

This species is currently considered to be a complex of several varieties and the species is variable in appearance. The varieties can be variable in ploidy level, with diploid, triploid, tetraploid, hexaploid, and others known. Diploid and polyploid individuals may occupy different types of habitat. The varieties intergrade with each other and they can hybridize with each other and with other Atriplex such as Atriplex corrugata.
