Pallida is very hardy, you almost can't kill it. It smells like grape kool aid.
Species Iris (Iris pallida)
This is the plain green leaved one. It also comes with a variegated leaf.
I have the plain green leaved one. If you want some in the spring, just give me a holler. I'd be glad to share, have lots of it.
If you look at the Superstition site you will find named pallidas also, like Beatrice.
