To kick off Earth Day here on Casa, I thought I'd show you a very cool way to bring a little green into a cramped-for-space home or garden. The ELT Easy Green Living Wall ($39 - $249) is a modular-living wall panel that you can buy pregrown or that you can plant on your own. Made of 100-percent recyclable plastic, it is environmentally friendly, not to mention aesthetically pleasing. A vertical garden of sorts, it's a great option for those lacking green space, but it also has a wonderful, modern visual quality that I've seen nowhere else. Each Living Wall looks unique, as its appearance all depends on which plants are used. There are numerous ways to use Living Walls; you can take a traditional route, using it as decor (like a planter), give it function, using it as a fence, or take a modern approach, livening up an exterior wall, as shown. What do you think? Would you buy one (or several)? I kind of want one . . .
