Green walls are glorious. Take the technology for green roofs and put it somewhere everyone can enjoy it. Regardless of any environmental benefits that may result, just think about how great it would be to coat your entire house with succulents!
The designer that everyone seems to watch is Patrick Blanc – read an interview with him here. He does these fabulous wall sculptures with plants. A steel frame is mounted onto the face of the building (leaving a gap between the frame and the wall), PVC sheets are attached and then felt is used as a rooting medium for the plants. His soiless system uses hydroponics (water with nutrients) to irrigate and sustain plant life.
Most green walls use some type of grid planter system using a frame, cells and irrigation channels. If soil is used as a potting medium, the cells are generally 2 – 4 inches deep and a lightweight moisture-retaining mixture is used. The home gardener can order cells that are slanted, to help keep the potting mixture in the wall.
There are lots of great examples of commercial applications – particularly in Asia and Europe, where green walls are used for company logos. With careful plant selection and planning, the walls can thrive most places – indoor and out.
It doesn’t have to be a full wall either – some designs use green panels like architectural punctuation. Here’s a recent article in Met Home about a garden wall installation.
Interior installations look like art. I wonder if it would give your living room that steamy conservatory smell?
