Ambrosia salsola, commonly called cheesebush, winged ragweed, burrobush,white burrobrush, and desert pearl, is a foul-smelling, scraggly perennial shrub in the (sunflower family) common in deserts of the southwestern United States and northwestern Mexico.
This species easily hybridizes with the white bur-sage (Ambrosia dumosa).
It is common on sandy desert flats, desert dry washes, and is weedy in disturbed sites in creosote bush scrub, shadscale scrub, Joshua tree woodland, and Pinyon juniper woodland, ranging from Inyo County, California, to northwestern Mexico.
It grows in sandy and gravelly soil, and sometimes on lava formations at elevations of 200–1,800 m (660–5,910 ft).
It is native to the southwestern United States (Arizona, California, Nevada, Utah) and northwestern Mexico (Sonora, Baja California, Baja California Sur), where it is a common plant of the local deserts, where it thrives on sandy soil, alkaline environments, and disturbed sites.
It is typically 2' to 3' in height. It drops about half of its leaves and some of its twigs in hot, dry summer conditions (drought deciduous).
Ambrosia salsola is a shrub sometimes attaining a height of 150 cm (59 in).
This is a perennial shrub which forms a sprawling bush up to eight feet high.
