I need to look at my pale peach irises as well. As with my quest for blue I was trying to find pink irises and wound up with several, maybe four or five, light peach ones that are very similar. These are older ones and I need to make some decisions about which ones to keep and which ones need to be relocated.
If I had the room I would never let an iris go. That would not be good as I would wind up with a tangled, jungle growth of weeds and irises due to over planting my physical limits. So, I guess it is all good that I don't have forty acres. LOL
