DistributionEssentially statewide, but may be absent from the northern mountains.

Native to the south-central US and Mexico, though the native range is obscure; introduced east to the Atlantic Coast.
AbundanceFairly common to locally common, but scarce in the central and northern mountains.
HabitatRoadsides, fields, other disturbed ground -- almost always in full sun.
PhenologyFlowers and fruits May-August.
IdentificationThis is an easily identified Oenothera, as it has large pink flowers -- about 2 inches across, though a few can be white. All others in NC have yellow to rarely white flowers. Masses of these can be seen along some roadsides, and when in full bloom present an unmistakable sight.
