Chrysothamnus viscidiflorus is a species of shrub in the family Asteraceae of the Americas known by the common names yellow rabbitbrush and green rabbitbrush.

Description[edit]

Chrysothamnus viscidiflorus grows up to about 150 centimeters (5 feet) in height, with spreading, brittle, pale stem branches. The leaves are up to a few centimeters long and may be thin and thread-like or up to 1 cm wide and oblong. They are glandular, resinous, and sticky.

The inflorescence is a bushy cluster of flower heads, each head 0.5–1 cm 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.[3]

Subspecies and varieties[edit]

Subspecies and varieties include:[4][5][6][7]

  • Chrysothamnus viscidiflorus subsp. axillaris (D.D.Keck) L.C.Anderson — desert slopes in Arizona, California, Colorado, Nevada, Utah[4][5][8]
  • Chrysothamnus viscidiflorus subsp. lanceolatus (Nutt.) H.M.Hall & Clem.Pennington County in South Dakota[4][5][9]

  • Chrysothamnus viscidiflorus subsp. viscidiflorusalpine talus in most of the species range[4][5][11]
  • Chrysothamnus viscidiflorus var. latifolius[4]
  • Chrysothamnus viscidiflorus var. serrulatus (Torr.) Greene — Utah, Nevada[4][12]
  • Chrysothamnus viscidiflorus var. stenophyllus[4]
  • Chrysothamnus viscidiflorus var. viscidiflorus[4]

Chemistry[edit]

Chrysothamnus viscidiflorus contains an unusual m-hydroxyacetophenone derivative, named viscidone, and chromanone derivatives.[13]

Distribution and habitat[edit]

The plant is widespread across of North American in 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,[14] as well as in South America in the Andean valleys of Chile and Argentina.

It grows easily in alkaline and saline soils, and thrives on soils that are rich in calcium.[15] 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.[15]

Ecology[edit]

It is a larval host to the sagebrush checkerspot and it is an important nectar source in the fall.[16] Range animals such as deer and antelope browse the foliage.[17] It often occurs with Ericameria nauseosa.[17]
