Bengal Trumpet
Thunbergia grandifloraAlso known as Bengal Clockvine, Blue Skyflower, Blue Trumpetvine, Skyvine
Bengal trumpet is a vigorous perennial vine celebrated for cascading clusters of lavender-blue flowers with pale yellow throats. Supported by a massive underground tuber system, its stems scramble up to twenty meters into forest canopies, often draping native trees in a dense leafy blanket. Although widely cultivated as an ornamental shade vine across the tropics, its aggressive growth has made it an invasive threat in many riparian ecosystems outside its native range.
