DistributionThroughout the Piedmont and most of the mountains. Present over most of the western and central Coastal Plain, but apparently absent near most of the coast and in the northeastern portion. Most references consider this species not native in the US, but Weakley (2018) states: 'Native distribution uncertain, but apparently native to the se. United States."

This species ranges from PA and IA south to GA and TX, seemingly absent from FL.
AbundanceFairly common to frequent in the Piedmont and most of the central and western Coastal Plain, but uncommon to infrequent in the mountains. Rare to absent in the eastern Coastal Plain. NatureServe does not consider it as a native and does not bother to give a Global Rank at all (= GNR).
HabitatThis is a species of disturbed places, such as roadsides, fallow fields, thickets, and edges of moist woods. These habitats are reason for being suspicious of its provenance in the US.

PhenologyBlooms from August to frost, and fruits shortly after blooming.
IdentificationWhen in bloom, this is a very obvious species, nothing else like it. However, vegetatively, it is just another heart-leafed vine. It is an herbaceous vine growing to 6-8' long, often twining. It has widely scattered alternate heart-shaped leaves, about 2-3" long and nearly as wide. Some plants or populations can have leaves with side lobes near the base, but in either case, once the flowers are seen, it is easily identified as this species. From many of the leaf axils grow the flowers, each one somewhat trumpet-shaped, about 1-1.5" long but only 2/3" across, and bright orange-red or scarlet in color. These flowers are much smaller than most others in the genus, and also are more tubular and not as flaring in a funnel shape. Another Ipomoea has scarlet-red flowers, I. quamoclit, but that species -- definitely not native to the US -- has leaves finely divided into numerous, very narrow segments (unlike any other NC plant).
Taxonomic CommentsSome old references placed the two scarlet-flowered species in the genus Quamoclit.
