Edible walls

The Dirt recently posted about the benefits of green walls (like green roofs, but vertical), highlighting their potential for urban farming. I think that while it's a really cool idea it definitely isn't for every situation. Like for me right now. See, while I wish I could try this out, I don't have a good place for it. I don't want to completely block my view out of the sliding glass doors, and I don't think they'd get enough sun if I put them to the side.

But, if I ever get to build a house or do a major renovation, green walls will definitely be on my "must have" list!
