...and we all growing this plant around here.
We love it, and it works great in hanging baskets also. Its also drought tolerant and goes right through other freezes unlike most Thunbergias.
The tall progressive flowering spikes are confusing but could be Thunbergia-like, as Sky Vine flower in short progressives ie.
I would really like to clearly identify this great plant for Central Florida (for one zone for sure)!
