Scarlet creeper is native to the southeastern United States, Mexico, Central America, and South America. It has become naturalized in many other parts of the world. It appears along roadsides, stream banks, old fields, thickets, and waste areas.
Plants: Vines, with thin hairless or slightly hairy stems, 3-4' (91-121 cm) tall, and may trail horizontally up to 10' (3 m).
Leaves: Alternate, heart shaped, often deeply lobed into 3 to as many as 7 segments, ¾-6" (2-15 cm) around, with smooth edges and sharp tips.
Flowers: Trumpet-shaped, in small clusters, with a 1½" (3.8 cm) long thin throat that flares suddenly to about 1" (2.5 cm) diameter at the end. The style and stigmas extend well beyond the flower. Pedicels (flower stalks) are ⅛-½" (5-15 mm) long. Blooms appear from July to November.
Fruits: ⅛-¼" (6-8 mm).
