Diagnostic: Thunbergia laurifolia is a sun-loving climber popularly used to cover fences and trellises. The leaves are distinctive with some serrations on its margins. The purple flowers are large with a darker tint of purple at the lower lip.

The flowers look exactly the same compared with Thunbergia grandifora (another commonly cultivated climber) but they can be differentiated easily from the leaf shape.

Interesting Facts: While the Laurel Clock Vine is nationally extinct, it is still possible to find them growing wild in young secondary forests. However, their occurence is very likely to be escapees from cultivation. The flowers are visited frequently by carpenter bees.
