MUD seems like the first place I think of when I think permaculture. They have a great site and offer a range of activities and workshops that are community oriented. The site is full of frugal ideas to live more self-sufficiently such as an amazing tool library, truck share program, and so much more. www.mudproject.org
The UM FLAT
project is a University project
led by students who are demonstrating
sustainable living practices. They are relatively new, but are developing an outreach / education component, recently hosting a Terra Madre event. The site has a mandala shaped permaculture garden, a hot box for extending the season,
chickens, a garage renovation that will be used as a community demonstration space, and quite a few other things. www.umt.edu/umflat
The PEAS farm has been increasingly using permaculture at their site. The barn is
straw bale, they have a great
root cellar with a living roof, they use a lot of reclaimed materials, their
tractor runs on a single-tank vegetable oil system, they are experimenting in the fields a bit with companion planting, herb and veggie spirals, and for the most part, the farm is all student run and they run a great CSA and a lot of their food gets donated to the Poverello Center and the Food Bank. Awesome!

Missoula has a great resource for
native plants. You can see their demonstration garden near the Kim Williams trail and Higgins Street, though I can't think of who the contact is.
I am sure there are many more, can anybody add to this list.
