About Big Saltbush (Atriplex lentiformis) Atriplex lentiformis is a species in the Chenopodiaceae (Goosefoot) family known by the common names Big Saltbush and Quail Bush. It is native to the southwestern United States and northern Mexico, where it grows in habitats with saline or alkaline soils, such as salt flats and dry lake beds, coastline, and desert scrub. It can also be found in nonsaline soils on riverbanks and woodland. This is a spreading shrub reaching one to three meters in height and generally more in width. It is highly branched and bears scaly or scurfy gray-green leaves up to 5 centimeters long and often toothed or rippled along the edges. This species may be dioecious or monoecious, with individuals bearing either male or female flowers, or sometimes both. Male flowers are borne in narrow flower clusters up to 50 centimeters long, while flower clusters of female flowers are smaller and more compact. Plants can change from monoecious to dioecious and from male to female and vice versa. This saltbush species and Atriplex canescens are the host plants for the Saltbush Sootywing and Pygmy Blue butterflies. This plant is used to revegetate riparian habitat in its native range. In the Lower Colorado River Valley and Gila River valleys of southwestern Arizona, southeastern California, and northwestern Mexico Big Saltbush can reach 3.5 meters (11 feet) in advantageous growing locales. The maximum height occurs where a groundwater source supplies virtually unlimited moisture; soil conditions are optimal for the quailbush, and other plants lose in competition, though arrowweed, tamarisk, and tumbleweeds are competitors; also mesquite.

Companion Plants
This plant is not often used in small residential gardens but is very useful on larger acreage and in restoration projects, especially where the soil is alkaline and there is subsurface water. Use with native grasses such as Deer Grass (Muhlenbergia sp.), Arrow Weed (Pluchea sericea), Mesquite (Prosopis glandulosa or pubescens), Desert Thorn (Lycium sp.), Alkali Goldenbush (Isocoma acradenia), and willows (Salix sp.).
