Linnaeus named this species in 1753.  Artemis was Apollo's twin sister and daughter of Zeus and Leto; she was the equivalent of the Greek Diana, goddess of the moon, the woods, and the wild, who, the legend states, derived so much good from plants of this kind that all such plants are named for her.  Intermountain Flora presents another etymology: the genus is named for Artemisia, historical queen of Caria (in present day Turkey) who was a "noted botanist, medical researcher, and scholar".  She was named for the Greek god.

Flower stems emerge from a tight tuft of very conspicuous, handsome, silvery gray-green basal leaves. The tiny stem leaves are clumped together, bristle-like.  Artemisia frigida is abundant on dry, gravelly hills and is widely distributed throughout the mountain states and east to Wisconsin.

"Frigida" is Latin for "cold"; the species was first collected in Siberia in 1803.

From the lowlands to higher mountains, Sagewort is quite common  --  but frequently unnoticed. It is found in all lower 48 states except Florida.  It grows from one to three feet tall, often in masses.  Silvery-sage-green leaves are from one to several inches long, narrow, sometimes entire, sometimes lobed or with a few small toothed notches.  Massed, tiny, downy, silvery-white flower buds are present for many weeks before they open into minute yellow flowers which in turn give way to brown seeds. (All three can be seen in the picture to the left.) 

Intermountain Flora indicates that this is a "highly complex species" with a number of subspecies. 

Sagewort is widely spread in the U.S. and the type species was, in fact, collected by Thomas Nuttall in 1810 or 1811 on the banks of the Mississippi near St. Louis prior to his departing for a collecting trip with the Astor Company up the Missouri River.  "Ludoviciana" means "from Louisiana", i.e., named for the Louisiana Territory, which encompassed St. Louis and most of Missouri as well as most of the land from the Mississippi west to the Rockies. It is common to have a species named for the place it was collected: "Virginiana", "Canadensis", "Arizonica".  Nuttall published his description of Artemisia ludoviciana in his 1818 two volume work, Genera of North American Plants.
