I have a sign post that needs a little sprucing up. It looks like a typical US metal stop sign post. It's in the shade about 70% to 80% of the day so that limits my options. Also, anything I do to it will have to be potted since it's concrete down around the base.

I was thinking about growing some kind of fast growing blooming vine or ivy. But I'm posting here because I'd love to hear some ideas. If I do go with a blooming vine or ivy, which one would you suggest?
