Oregon's Permaculture Networking Site in Corvallis, OR
OK, so I'm gaining some enthusiasm for the whole high desert permaculture concept. Been doing some research regarding fruit trees that will not only survive, but thrive in the harsh high desert conditions of eastern Oregon, Washington, and Idaho. So far, pomegranates are starting to look really good, and I remember from my time in Afghanistan that pomegranate trees were pretty much everywhere. For those of you who don't know, Afghanistan is basically one big high desert, with altitudes between 2,000-7,000 feet, temperature extremes from sub zero to well over 150 degrees F (!) That's not a typo, I experienced it myself for two weeks in August of 2006. If trees can survive and produce under those conditions, then eastern Oregon should be no problem. So I need some suggestions. Any source of seeds or young trees for establishing a food forest in the high desert would be very much appreciated. I think I already have a source for Russian Pomegranates (www.dave'sgarden.com) and would like to find some more. I want to have the most diverse forest garden that I can get with desert hardy trees that can deal with the low rainfall and temperature extremes that we get. I also need some suggestions of leguminous trees, and non producing support species, ground covers, and etcetera.
Thanks all in advance!
