Delphinium carolinianum Walter ssp. carolinianum . Ozark Larkspur, Prairie Larkspur, Carolina Larkspur, Blue Larkspur. Phen: (Apr-) May-Jul. Hab: Rocky woodlands, granite outcrops, Altamaha Grit outcrops, blackland prairies, calcareous glades, moist sandy woodlands associated with longleaf pine. Dist: IL west to e. KS, south to LA and TX, with disjunct occurrences eastward in SC, GA, AL, Panhandle FL (Gadsden County), and MS; questionably reported for c. TN. The flowers are a pale to medium blue. This species has been reported for NC (by C) and ‘north to Va.’ (by F and S). I know of no documentation for its past or present occurrence in NC or VA, but its presence in those states is plausible.
