South facing wall help pls?

I have a south facing wall that I would like to plant some "things" in but I don't know what. It's a small area, 5 meters long 1 meter wide. I would like all year round green with as low as possible maintenance.

Any ideas?

 

by "in" do you mean in the wall itself, or at the base of the wall to climb up it, or grow against it?

 

Not really climb up it, it's not a strong fence so I'm thinking more shrub type of action!
