I have 2. Iris spuria 'Golden Lady', Iris spuria 'Lemon Delemma'
I have them planted with my Japanese and Siberian iris. No special care.
They do not seem to be evergreen. I am in zone 5. I just went out with flashlight in hand, they are all brown but do have a few green new growth. Never noticed that before:) of course, I was not looking...
