It is called Dichoriste thunbergiflora. Say DI-kor-EEST thun-BERJ-eh-FLOR-a. It's a mouthful, right? I think that means that it has flowers kinda like Thunbergia, or Black-Eyed Susan vine. Yes the flower shape is similar, a tube that flares out at the end with a dark center. Black Eyed Susans are Orange with black throats. Gotta love Latin. It tells you right there whats what(if you know).
It has grown to about 3' tall and 2' wide. I gave it a haircut last year to make it bushier. It is growing on the east side of our house. But it gets a LOT of sun.
I love the color.
