The vine is called Queen's Court here in Brackettville, I don't know what it really is. It's an almost obnoxious pink color. We had an influx of butterflies in the spring, it was amazing, and the vines were just dripping with Sulphers and Snouts. It was amazing, did I already say that? Click on the first image (or any of them for that matter) to see it better.
Gotta love Google:
n. A common name, one of many, for the open and airy subtropical vine Antigonon Leptopus, which has heart-shaped green leaves and long, trailing sprays of small rosy-pink flowers. Also called Rosa de Montana, Corallita, and Queen's Wreath.
