Ipomoea hederifolia (Scarlet Morning Glory)

Native to tropical and subtropical America, this annual vine climbs by twining around surrounding vegetation. Its leaves are heart-shaped and may have three to five lobes. Scarlet flowers have long, narrow tubes and broad, nearly flat mouths, with stamens and styles projecting beyond the petals. Rounded capsules release dark, hairy seeds. It grows in open and disturbed vegetation. In Colombia, it occurs from lowlands to about 5,280 feet. The species has been introduced widely beyond the Americas. Photographed in Baru and Tubará, Colombia.
