Design an urban jungle (& get some test plants)

I've just moved in to a new flat and have grand visions of a beautiful green space - but unfortunately don't have the green thumb to make that happen, so want someone to advise me on what plants would work best and look amazing. I'll send photos of the three areas I want to put greenery - above the fireplace, the bathroom and the reception room. I'd like you to suggest what plants would be best in each space to make my urban jungle dreams a reality. Please also buy and deliver a few example plants that I can use as testers to make sure I don't kill them immediately before installing the full vision.
