Could also be Primrose Jasmine (Jasminun mesnyi).
https://duckduckgo.com/?q=Prim.... Looks like the leaf on the one I moved this past spring from my city yard down to our cabin property. They get huge, grow fast and root everywhere a cascading branch touches the ground. If you're considering one, be sure it's in a place that won't become problematic (which mine did in just 2 years).
