How to identify Orange clock vine (Thunbergia gregorii)

Orange clock vine, also known as Golden glory climber

Orange clock vine is an evergreen vine reaching heights of 8-10 ft (2.4-3 m) or spreading as an extensive groundcover. The vine features 1-inch (2.5 cm) long, triangular, hastate-based leaves with toothed margins and sparse, slightly hairy surfaces. The distinctive, bright pure orange flowers bloom year-round, lacking the dark eye characteristic of related species. The slightly winged petioles support the foliage and blossoms, further differentiating orange clock vine from its relatives.
