I was browsing through my RSS feeds this morning and come across this fantastic article in Wired which is basically about permaculture though they don't use that word. Instead they discuss gardening as a process of careful design described as terraforming... essentially, permaculture. Excellent color design diagrams ranging from small gardens on apartment terrace or big garden spaces in a suburban or rural setting. If you are the least bit interested in taking gardening to the next level this is really worth a look, a great introduction and a nice surprise that it came from WIRED!
