Thunbergia grandiflora (Blue Trumpet Vine) is a vigorous twining evergreen vine, often grown as an annual, with large, heart-shaped, bright green leaves, 4-8 in. long (10-20 cm), and attractive trumpet-shaped lavender-blue flowers, 3 in. across (7 cm), adorned with pale yellow or white throats. Born in elongated clusters on long, drooping branches, they bloom throughout the summer and fall, year-round in tropical climates. Prized for its fast climbing habit, Blue Trumpet Vine is perfect for hiding an unforgiving fence or scrambling through arbors and trellises and looks stunning in hanging baskets.
