Chrysothamnus viscidiflorus is a species of shrub in the daisy family known by the common names yellow rabbitbrush and green rabbitbrush. It is native to western North America, from British Columbia to California to Nebraska, where it grows in sagebrush and woodland habitat. It grows easily in alkaline and saline soils, and thrives on soils that are rich in calcium.[1] It rapidly establishes in disturbed habitat, including burns, flooded washes, and rockslides, so it is a valuable shrub for revegetating damaged land such as overgrazed rangeland and abandoned mining areas.[1] This shrub grows up to about 1.5 meters in height with spreading brittle pale-colored stem branches. The leaves are up to a few centimeters long and may be thin and thready or up to a centimeter wide and oblong in shape. They are glandular, resinous, and sticky. The inflorescence is a bushy cluster of flower heads, each head one half to one centimeter long. The flower head is lined with sticky yellow-green phyllaries and contains several yellowish protruding flowers. The fruit is a hairy achene a few millimeters long with a wispy pappus at the tip.

C. viscidiflorus contains an unusual m-hydroxyacetophenone derivative, named viscidone, and chromanone derivatives.[2]
