Oligosporus dracunculus

Artemisia dracunculus. Synonym: Oligosporus dracunculus subspecies glauca. (Wild Tarragon)
Asteraceae (Sunflower Family)

Foothills, montane. Rocky outcrops and meadows, roadsides. Summer.
Horse Creek Trail, August  31, 2005.

The impression one has of this plant as one approaches it is of a bushy clump of strong, green, vertical stems with contrasting, lighter colored, tiny spheres dotting the upper third of the plant.  Wild Tarragon is easy to spot from many feet down the trail, and it is quite common in open meadows and along roadsides in the Four Corners area. 

Plant aroma can vary from none to a very pleasant and even strong Tarragon scent.  Intermountain Flora indicates, " Aromatic and inodorous forms [of Wild Tarragon] are widely scattered in both North America and Eurasia, as are glabrous and shortly hairy forms.  The leaves are used for flavoring, especially in some parts of Europe." 

The plant was first collected in Siberia and was named Artemisia dracunculus by Linnaeus who also named the genus in 1753.  It was renamed Artemisia glauca in 1831.  The genus name "Oligosporus" (from the Greek for "few spores"  --  perhaps because the disk flowers are infertile) was given by Cassini in 1847.   In 1981 it was given the name that Weber accepts: Oligosporus dracunculus subspecies glauca.  Kartesz accepts Artemisia dracunculus. 

From Latin we get "Drac" for "dragon" and "unculus" for "little".

The tiny spherical dots are the flower heads and seed heads. (See close-up photographs below.)  The rose/purple behind the ruler are the flowers of Erigeron speciosus.
