Most really tall flowering plants you would probably have to do from seed. Clematis is tricky I think.

But there are ivy's, and other vines like that. Those would be available in stores. If this is in full sun? Try some green beans!

You could do bushes in front of the fence... upright cedars are pretty elegant (but they would cost more money in the beginning.)

What are your watering potentials there? Can you reach with a hose? If you cannot water, you'd have to have something that likes dry conditions. I'd consider light and water first, then move on to the other choices based on those.
