This came as a mystery bonus about a year after we planted a yucca we dug up from a friends property. He had a friend who did landscaping and the unwanted plants from clients ended up in a big pile on a hill. The closest I can come up with is Japanese hops with a google search. The vine is "sticky" to the touch and instantly "grabs" your skin or clothing. It seems to be fairly invasive so I've been keeping it in check. Anyone?
