Absolutely my favorite vine! My grandmother called it 'Queen's Crown' and I still do. It's also called Coral Vine by the younger generation. The proper name is Antigonon leptopus.

It comes in the most often seen pink color, but also what's called red, but is more of a very dark pink, and there is also a white form, which I had at another house. I'm still looking for another white one. The pink one I have was labeled white when I bought it. A seeding I gave to Jolana was pink and white so I guess it carries the white gene.
