Aack! Pull it out ! get the roots and runners too!
That is Skunk Vine an incredibly invasive vine that will grow enough biomass to smother ALL your good plants. Get it out before the flowers make seeds because every seed will germinate.
When we first moved to the Nature coast about 2 years ago, it was in the back yard and the hummingbirds seemed to love it.I had to put up 8 feet of fencing to keep the dog in the yard of our rental house and within one summer the whole 8 foot perimeter fence was covered in Skunk vine.Then we found out what a problem it was from Native Plant folks. It really is a bad plant.
