It looks like Dipogon lignosus, cape sweet pea vine. Here is a link that might be useful: Dipogon lignosus, cape sweet pea vine

Its, perennial vinca. Sounds like you have the white variegated variety (I've got the yellow, my,self). MOW it, it will keep it in check and really make you feel better. You won't kill it, I promise. Now, if you want to kill it, why not try and see if anyone on the plant exchange forum will give you something you want for it instead. If you trade away much of it, but still want to kill it, ask again and I'll tell you how. ~Chills

Thank you both for your help! If it ever gets flowers, I know it'll be a lot easier to I.D., but, as long as it's not a weed (or the very dreaded poison ivy) I'll leave the mystery vine be, for now, and see what happens.

I have looked thru all the stuff I could find on Virginia Creeper and I am still convinced this is not it. As I said, I do have VC in the backyard, so I have a direct comparison. I know they do both have multiple toothed leaflets but these are all 7 not 5 (the other VC vine has occasional leaves of 3 and 7 but is predominantly 5) and MOST OF ALL VC's stem is not sticky at all. This one is adhesive in the extreme (not prickily or thorned, just very sticky). Thanks for the guess though. Anybody have any other thoughts? Leslie
