Hi, To spare the long sad story, i'm going to shorten this up. I have a friend with this vine in his backyard. His gf planted it and it decided to flower the day she died when she was hit by a drunk driver. He really wants to be able to figure out what she planted (no longer has the envelope) so he can fill the backyard and trellace with them next year. We live in Wisconsin - though that may not help for anything other then climate it grew in. It was planted from a packet of seeds, so its not like its native. Your help would be GREATLY appreciated! Thank you, Robert
