Hi Gingernutranger,
I am so shocked I did not see this post myself. This has been a little bit since you posted. I sure hope you come in and check on this post, because I think I found something really nice!
Here, on Craigslist in Seattle, Washington (your town),
http://seattle.craigslist.org/skc/grd/1366711813.html , this is a listing for a fantastic plant sale. It is tomorrow 9/11. ( I know, what timing ):/
Anyways, look down the list you will see Iris!!!
I sure hope you see this. If you miss it, you can always keep your eye out for other things on Craigslist, or you can simply add a posting for what you are looking for under "Wanted", I am sure there is some elderly person just dying (sorry), just hoping to find you so that you can come clear out all the iris that has taken over.
Wishing you luck in your quest. I always get new Iris locally from folks who want to rid themselves of the excess rhizomes. My next Iris will be a brightly colored Bearded Orange Iris. I doubt it has a name but I saw it blooming this Spring. I loved it!
