Leucosyris arida

Leucosyris arida is an annual plant in the family Asteraceae, known by the common names arid tansyaster, desert tansyaster, and Silver Lake daisy. It is native to the very arid deserts of northern Mexico and the southwestern United States, and usually looks straggly and not very attractive. But in years with very heavy rainfall, it fills out and becomes rounded and bush like. Leucosyris arida is widespread throughout its desert habitat in Arizona, Nevada, California and Sonora, including disturbed areas such as roadsides. It can be found in very arid, open sandy and salty soils, up to 3,000'. It grows in creosote bush scrub, alkali sink, and desert dry wash areas in the central and eastern Mojave Desert from Barstow, California to Arizona and Sonora, Mexico....read more on Wikipedia.
