    Erigerons, commonly called "Daisies" or "Fleabanes", are a large and complex genus.  This web site shows 24 of the 48 species in the Four Corners area;  there are 130 species in North America and 200 world-wide.

     Erigerons have yellow disk flowers and numerous narrow ray flowers that are white, pink, or purple (but not yellow).  They grow from the semi-desert to the alpine regions and although a few are uncommon, most are very common.

      In 1753 Linnaeus gave the genus its name from the Greek "eri" ("early") + "geron" ("old man", as in "geriatrics", the study of old age processes and problems).  Perhaps the Greek name refers to characteristics of some now unknown plant or perhaps it refers to the early flowering of many species and to the bristly pappus of the developing seed, or perhaps to the puffy, grizzled appearance of the mature seed head.

Erigeron concinnus is a common Erigeron of the lower elevations.  It is fairly easy to recognize because it looks blurred due to a myriad of fine hairs that project from leaves and stems. A close look refocuses our eyes and we see the trickster hairs. Erigeron concinnus commonly grows in 4-8 inch diameter clusters with multiple stems topped by nodding buds. Stems and buds eventually straighten and buds open to white or light blue flower heads.

There is some disagreement over the name of this plant.  It was first named Distasis concinna by Hooker and Arnot in 1839 and has since undergone several name changes.  Weber, The Flora of North America, and Kartesz accept Torrey and Gray's 1841 Erigeron concinnus; Welsh and Intermountain Flora accept Dorn's 1988 Erigeron pumilus variety concinnus.  "Concinnus" means "pretty".
