If you don't have a "green thumb," maintaining any type of plant life in the house can be difficult, but instead of hiring a gardener for your indoor plants or switching to artificial flowers, you can install a plantwall. The Plantwall is a vertical pant installation that is "almost like being outside inside." It has an integrated irrigation system that distributes water and fertilizer throughout the wall, so there should be no reason for the wall to be anything other than lush and green. The price depends on the size and shape of the wall you want, as well as on the type of plants that you want to showcase.
