I have this vine growing in a pot on my deck. My mom gave me a clump of it a couple of years ago, and when I got home, I put it in the pot while I decided where its permanent home should be. Needless to say, it never got transplanted. She may have told me what it is called, but I don't remember.
Most of the time, I forget it's there, because it stays dormant most of the year. With this summer's drought, I figured it had finally died a sad, neglected death. Then we had some rain, and it leaped from its sleep and began its routine.
First, it extends it long, spindly vine - reaching and searching for anything to attach its little suckers to. If it can't find something, it contorts itself backwards and attaches its new growth to itself. Occasionally, it sets forth a little red flower, such a brilliant red that it's almost fluorescent. The flowers only last a day, so I have to act fast if I want a picture.
And with all that fascination right on my deck, that's how this nature study came to be.
