Hymenoclea salsola is a flowering plant in the daisy family known by several common names, including white burrobrush, cheesebush, and desert pearl. It is native to the southwestern United States and northern Mexico, where it is a common plant of the local deserts, where it thrives on sandy soil, alkaline environments, and disturbed sites. This is a perennial shrub which forms a sprawling bush up to eight feet high. It has thin branches and narrow, needlelike leaves. The foliage has a pungent cheeselike scent when crushed, a trait which gives the plant the common name "cheesebush". It is covered in plentiful white or yellow flowers and then pearly, winged fruits in white, yellow, or pink. This species easily hybridizes with the common ragweed species Ambrosia dumosa.
