Recently I received the Midwest Permaculture's newsletter. They had a link to a great article about permaculture in Time.com. It would appear that the permaculture concept is becoming more "mainstream". Here is a link to the Time.com article by M.J. Stephey titled "The Incredible, Edible Front Lawn": http://www.time.com/time/nation/article/0,8599,1816764,00.html
Midwest Permaculture's website is http://www.midwestpermaculture.com/
It's a great website and they have some wonderful videos displaying their projects. Also, their newsletter is informative and encouraging. You can sign up for their newsletter at their website.
For more information about edible landscaping, here's a plan by horticulturists, Travis Beck and Martin Quigley: http://www.postcarbon.org/files/EdibleLandscaping.pdf
