This is taken in a show home that we did - we suspended glass terrariums with faux plants and laid moss on the floor as a unique way to accessorize it. I think you could do a functioning version of this idea with wall mount planters and real plants and use faux grass on the floor that has a woven plastic backing with a hole cut out for the drain (this is floral moss).

LOL, Stock up on the Lamisil and Tinactin!

I wish I could use the laughing emoticon here. :)
