Since you were not very specific about how shady your area is, we are going to search for vines for your purpose that will tolerate both "shade," less than 2 hours of sun a day, and "part shade," 2 to 6 hours of sun daily. Most flowering plants will get better bloom with an increase of sun, so hopefully you would consider that your space had from 2 to 6 hours of sun a day.
