Did you know: the big sagebrush is named for its pungent odor, which resembles that of the common sage. Although this shrub may smell quite good to humans, it is likely that the volatile oils responsible for the sagebrush's pleasing fragrance actually serve to deter herbivores. Even if you don't intend to take a bite of the sagebrush, however, watch out when you smell it! The pollen of this plant are thought to be a major cause of hay fever.
