DistributionThroughout the Coastal Plain and the eastern and central Piedmont, but oddly scarce in the Sandhills region. Ranges west only to Guilford, Rowan, and Cleveland counties.

Mostly Coastal Plain, from NJ and PA south to northern FL.
AbundanceGenerally infrequent to fairly common in most of the Coastal Plain, and uncommon in the Piedmont part of the range; generally rare in the Sandhills.
HabitatMesic to dry Longleaf Pine--Wiregrass uplands and flats, open pine-oak-hickory woodlands, woodland clearings, roadsides, powerlines. Tolerates fire rather well. Its scarcity in the Sandhills is strange, considering its dry and often sandy soil habitats.
PhenologyFlowering and fruiting April-June.
IdentificationStems grow mostly 1-2 feet tall from a rosette of 2-3 pairs of broadly ovate to nearly rounded basal leaves. There usually is another pair or 2 of much narrower stem leaves. The stems are topped by a branched inflorescence of several to many rather large heads, the rays yellow and the disks orange-yellow. This is a very handsome plant, as well as quite distinctive in NC!
