Rabbitbrush
Rabbitbrush is a common name for shrubs, principally of the western United States, in three related genera of the family Asteraceae:Chrysothamnus — about seven species in the United States, including Greene's rabbitbrushEricameria — about six species in the United States, including gray and Parry's rabbitbrushLorandersonia — about four species in the United States, including Bailey's rabbitbrush and spearleaf rabbitbrush
Taxonomy for these genera has changed recently; previously, the rabbitbrushes in Ericameria and Lorandersonia were included in Chrysothamnus. In each of these genera, not all species are called "rabbitbrush"; most Ericameria, for instance, are called "goldenbush", and only a minority are called "rabbitbrush".
