Thank you so much Ron. She has been propagating this and is quite successful with it. They make their own trllis there shaped like an umbrella and let this vine cover it. She wanted different varieties of it that is why it was very important for me to know its true name. Do you know of any sources?
Here's a pic of their umbrella trellis...

There is another species called Ipomoea microdactyla but the only source that I know is here in Florida and does not ship plants.
