Green rabbitbrush (Chrysothamnus viscidiflorus) can most easily be distinguished from the more common rubber rabbitbrush (Ericameria nauseosa, previously also in Chrysothamnus) by its twisted green leaves.  In addition, stems of green rabbitbrush are glabrous (ssp. viscidiflorus) or finely short-hairy (ssp. lanceolatus), while those of rubber rabbitgrass are covered by matted felt-like hairs.

The common subspecies of green rabbitbrush occurring in the Boise Front is the narrow-leaved form of ssp. viscidiflorus.
