I never worry about whether an Iris will do well for me or not. If I like it, I get it. In all the (forty-something-omigod) years that I've grown Irises, I've only ever had one variety fail. For the life of me I can't remember it's name. It was a Ghio Iris -- I remember that. Anyrate -- the only way that you'll know if an Iris will do well for you is to try it. I've found Irises to be very forgiving plants. If they can possibly get along, they will.
