Chrysothamnus viscidiflorus is a North American species of shrub in the daisy family known by the common names yellow rabbitbrush and green rabbitbrush.


The plant is widespread across much of the western United States and western Canada, from British Columbia and Montana south to California and New Mexico, with a few populations in the Black Hills of South Dakota and in western Nebraska.[2]

Chrysothamnus viscidiflorus grows easily in alkaline and saline soils, and thrives on soils that are rich in calcium.[3] 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.[3]


Chrysothamnus viscidiflorus grows up to about 150 cm (59 in; 5 ft) in height with spreading brittle pale-colored stem branches. The leaves are up to a few centimeters long and may be thin and thread-like or up to a centimeter wide and oblong. 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. The species grows in sagebrush and woodland habitat[4]

Chrysothamnus viscidiflorus contains an unusual m-hydroxyacetophenone derivative, named viscidone, and chromanone derivatives.[5]
