Duration: Annual Nativity: Native Lifeform: Vine General: Annual herbaceous vine; stems twining, often growing on other shrubs; herbage mostly glabrous. Leaves: Alternate along the stems, on slender petioles 2-9 cm long; blades 2-10 cm long and 1-7 cm wide, broadly heart-shaped (common), but can also be ovate or palmately divided into 3-5 lobes; leaf tips acute to acuminate; upper leaf surface bright green and lower surface glabrous to pilose. Flowers: Showy and bright red, in clusters of 3-7 flowers on long peduncles (3-20 cm long) from leaf axils; sepals 5, unequal in length, 3-5 mm long, often tipped with a green spreading awn 3-5 mm long; corolla red to red-orange, trumpet-shaped, about 2 cm long with a long narrow throat and short, abruptly spreading limb, the limb 1 cm or more wide. Fruits: Capsules 7-8 mm wide, globose with a short, pointed tip to 2 mm long; containing 1-4 seeds, these ovoid, black or dark brown, and finely tomentose. Ecology: Found in disturbed areas, roadsides, chapparal, oak woodlands, and pine forests, from 2,500-9,000 ft (762-2743 m); flowers May-November. Distribution: MN, IA, south to TX and west to AZ; south to s MEX. Notes: Distinguished from other regional Ipomoea spp. by being hairless on leaves and stems (sometimes hairs on nodes or undersides of leaves); having variable-shaped leaves, often with divided and entire leaves on the same plant; hairless sepals; and especially the red, trumpet-shaped flowers. There is a long history of mis-naming this species as Ipomoea coccinea. Ethnobotany: Unknown, but other species in the genus have uses. Editor: LCrumbacher 2011, FSCoburn 2015, AHazelton 2017
