Rabbitbrush (Chrysothamnus species) - Two species of rabbitbrush occur in the Mid-Columbia: gray rabbitbrush (Chrysothamnus nauseosus)and green rabbitbrush (Chrysothamnus viscidiflorus). Both grow in a variety of habitats, but are most abundant in areas with sandy soils. Rabbitbrush sometimes forms pure stands, but is more frequently a co-dominant with big sagebrush. Both species are deciduous and have narrow, elongated leaves; gray rabbitbrush leaves are covered with fine white hairs, while those of green rabbitbrush are hairless and somewhat sticky. Both bear clusters of small, bright yellow flowers in late summer.
