They are amazing Gilly! They look healthy to me...no rot, bugs or disease as far as I can see. The fact that they are so far above ground indicates that, beings you are in a climate similar to mine, they have had some frost heave. Don't transplant just yet...but instead, do like I said and cover the tubers (rhizomes...as I think they are bearded or beardless iris) with a few inches of soil/course sand mixture. Sprinkle them with a small amount of low nitrogen fertilizer now. Don't do it again till after they have bloomed and lost their flowers and you have let them "rest" (gorgeous flowering plants like that show off with blooms and then get so exhausted that they need a rest period) and divided them and put them in a sunnier location! If you follow what I said above (about dividing and a sunnier location), next year you will have double your pleasure!
