Yes, snarfie, i do believe it is an Ipomoea lobata...first two leaves are practically identical. Thank you so much for heading me in the right direction. Nice vine, but not so much for a garden catering to the nectar lovers and host plants for butterflies. I have a butterfly garden by design which turns out to be a hummingbird and bee garden by default
Unfortunately the robust and hopeful little vine is history. Still there are Ipomoeas everywhere here and although i feel badly for having pulled it up, i think i'll get over it...after a little while
