Sure thing Marilyn. I've never been stung by any of the wasps around the irises, they seem pretty intent on the blooms. That does always keep me from cutting any because they sometimes sit on a bloom and seem to look at me, daring me to challenge them! I've always felt like spurias would be a good cut flower- they have good substance. If I could just remember to go out and cut some at night! Being tall, they make a good back of the border plant anyway and that helps keep the wasps away from the viewer a bit.
I've read that supplying moisture for the first couple of years is recommended, that they need time to settle into the garden before they are so drought tolerant. I never really paid enough attention to the hybrid I got from Dee, so I think that is one reason it has been so slow to do anything. It did survive though, and that's saying something!
