What would work someplace with lots of water? I would love to hide some UGLY post for my back porch but since the water runs off the roof right on that spot I'm not sure what I could use. I know that climbing jenny works in some spots of the yard but I really don't like the look of it.

My idea was to have a big square pot built around each post and have the vine climb up. I'll include a picture so ya'll can get a better idea of what I'm rambling about.

Please excuse the mess this is my first year of trying to grow anything so I'm messy AND clueless as well as I'm having siding put on the house.
