DistributionThroughout the state, but sparse on barrier islands and the Outer Banks.

N.S. to WA, south to central FL and TX.
AbundanceGenerally common to very common statewide; locally abundant. Scarce on the Outer Banks and barrier islands. This is our most common fleabane species -- excluding the two "horseweed" species in the genus.
HabitatDry to mesic or xeric openings and clearings in a wide variety of open woodlands, especially where pine dominates, outcrops, barrens, roadsides, powerlines, fields, and disturbed areas.
PhenologyFlowering and fruiting Late April-October.
IdentificationPrairie Fleabane is an annual that typically grows 1-2.5 feet tall, usually with basal leaves senesced by flowering time. Stems leaves are narrow and rather few in number. Heads are produced atop acsending branches and form a rather flat-topped array, with numerous bright white rays and yellow disks. Heads are fewer-flowered and smaller than those of Annual Fleabane (E. annuus). Prairie Fleabane is generally more slender and smoother than that species.
Taxonomic CommentsIt has been divided into a number of other varieties or subspecies, depending on author consulted, but none of them occur in NC.

Other Common Name(s)Rough Fleabane, Common Eastern Fleabane, Daisy Fleabane, Lesser Daisy Fleabane. This species is often called Daisy Fleabane, but so too is E. annuus, and thus the need to abandon that name on this website.
