I have a natural rock face, about 20' high, bordering the street as you approach the base of my steep driveway. The rock was probably blasted at some point to create the street and as a result is fairly irregular; it currently has the odd scrubby shrub or seedling pine growing out of pockets. I would like to plant a vine(s) that would be capable of growing up that face with minimum intervention from me. The area faces southeast and gets morning sun, then shade from noon-ish on. Ideally, something that grows quickly, has a good flower, is relatively full, and has reasonably rapid growth. I'm in zone 5b. Any ideas, and does anyone know if wisteria would work, or if that would need me to add supports for it to attach to?

Thanks!
