I was really glad to see the No Roots posts because I looked for this info last year. A vendor sent me a rhizome with no roots. I wasn't sure whether to plant it, and I am happy to say I did and not only did it grow but it bloomed the next Spring. Now the bad news: I have not seen it for several months (went underground). This happens here in our desert heat and they usually come back but I am extra concerned about this one because of it's rough start. It is Consipracy and the bloom was absolutely gorgeous so I am hoping and praying I see it again. But I may find out yet that there are delayed issues with No Root Rhizomes.
Also, another "The Amazing Iris" story. I had a rhizome that I had separated to give to friends but had one more than I needed of one type. I left the Rhizome on a chair arm outside, fully meaning to re-plant it when I had time. It managed early on to drop from the chair to the patio cement. One month went by and then two months and there it stayed. Then we had frosts and I finally felt bad enough I put it back in soil and the next Spring it grew just great, as if it had never left the ground. I was impressed to say the least that even laying outside in a freeze did not kill it. But I should add, the variety this happened with is pretty hardy.
