| Distribution | Statewide, and presumably occurs in all 100 counties. Seemingly scarce in the eastern counties.
This is a very widespread Eastern species ranging from NY and southeastern NE, south to southern FL and central TX. | |
| Abundance | Common nearly throughout, though somewhat less common in the far eastern counties, and in some far southwestern counties. | |
| Habitat | This is a species of a great variety of open habitats, without regard to soil moisture, though it somewhat favors dry soil over wetland soil. It is a thicket and edge species, growing over other vegetation in dry places as well as in marshes and other wetland openings. It is most often seen in mesic wooded borders, thickets, and roadsides. | |
| Phenology | Blooms from May to September, and fruits from July to October. | |
| Identification | This is the most common of the certainly native morning-glories, a familiar species to biologists and to the public. It is a somewhat robust, herbaceous vine, growing to 10-15 feet long, and trailing or twining. The scattered alternate leaves are cordate, with a fairly long an pointed tip and a cordate base, the blades averaging 3-4 inches long and somewhat narrower. The flowers, in axils, are quite large, as large as any in the genus, being white, funnel-shaped, and about 3 inches long and wide, with a deep red to purple center. Though some individuals of the abundant weed I. purpurea can have white flowers, these have pink lines on the inside and do not have deep red throats. | |

| Other Common Name(s) | Wild Sweet-potato, Manroot, Man-of-the-earth, Wild Sweet Potato-vine. For whatever reason, this native species has never had "morning-glory" as a part of any often used common name. | |
