Thunbergia laurifolia, commonly known as Laurel Clockvine, is an evergreen or semi-deciduous perennial vine native to the moist deciduous forests and along forest edges in Southeast Asia. It is a fast-growing herbaceous climber that can reach lengths of over 20 feet (6 meters), with a sprawling habit that makes it suitable for covering trellises, fences, and arbors. The vine’s leaves are heart-shaped, and it produces large, showy, sky-blue to lavender flowers with a pale yellow or white throat. These trumpet-shaped flowers are approximately 3 inches (7.6 cm) in diameter and bloom almost continuously throughout the year, particularly from summer to fall, adding a splash of color to tropical gardens.

Laurel Clockvine is valued for its ornamental flowers and its ability to cover unsightly structures quickly. It is often used in tropical and subtropical landscapes for screening and as a ground cover in large areas. In cultivation, it requires well-drained soil, regular watering, and thrives in full sun to partial shade. While it is not particularly drought-tolerant, it can withstand short dry periods. It is not known to have significant disease or pest problems, but it can become invasive outside its native range due to its rapid growth and prolific seed production. Gardeners should be cautious and check local regulations before planting.CC BY-SA 4.0
