_Artemisia frigida_ Willd., commonly known as wild sage, mountain
sage, pasture sagebrush, and wormwood sage (figs. 3 and 4), is a hardy
perennial 6 to 20 inches high, with a woody base and white silky
leaves. The numerous yellow flowers, arranged in a racemelike head,
possess a strongly camphoraceous odor. The leaves are also strongly
aromatic. The plant abounds on dry sandy hilltops from the Dakotas west
to Idaho, north into Canada, and as far south as Texas.
