Linnea -- are you saying that you'd like a couple more Alien Mist? Or some other Space-ager?
Lesle -- I am still dividing. For my own purposes (moving Irises from the temp bed next to the garage, to Iris Lane as I clear weeds and build up soil) -- and have been sharing my extras locally. Depending on your climate, and specific bed location -- I don't think it's too late to share. I've planted Irises as late as mid-November here, and had them all settle happily in and bloom in the spring (very mild winter that year). On the other hand -- I've lost Irises that I planted in July and August because of an unusual winter with a freeze/thaw-freeze/thaw pattern that just heaved my rhizomes right out of the soil. So I don't think you can be certain about any of it.
I will happily send you Alien Mist right now, or after bloom in the spring -- whichever you prefer.
