Hi, could you possibly complete your persona profile with your location (city, obviously you're in Idaho). That way we can answer your questions and make recommendations based upon your climate, including altitude etc. Even Idaho has a fair amount of variation, from desert to mountains.
I plant iris in my daughter's garden in Salt Lake City, and 'Orange Harvest' has done very well for us there. She just sent me a picture a few days ago of a clump we moved from her previous house. It has doubled in size in 2 years, and is in bloom now. (sorry, it was a texted picture, so I can't move it to show you)
