Thunbergia grandiflora is a twining, flowering perennial vine with leathery elongated heart shaped leaves and flowers in colors of sky blue to light violet. There is also a white flowering variety. This vine is fast growing in the south and a beautiful addition to the garden.

I have mine on an arbor and in the spring it comes up from the ground and is a very fast grower. It starts blooming around July in my area. It is a beautiful shade of blue with a yellow throat. I cut mine back down to the ground in the winter time before the first frost hits and I also mulch it. Comes back every spring.
