Hi Roger You've been growing Iris cycloglossa longer than I have, but by following the advice given me when I bought the plant, I have had it flower, in a container. I was told to give it a good draining soil in a deep pot, and while in growth to keep it in a saucer of water. I let the plant dry out in summer, but not bone dry nor baked in full sun. It's tucked into sawdust under the eaves in the fall, where only the strongly windblown fall and early winter rains can occasionally reach it. Once in growth, and after the danger of a deep freeze is reasonably past (wasn't last year fun, thought), it's back into a saucerand a more exposed location. Hope this has some element that is different than you are already doing, otherwise .... Dave B - Tumwater, Washington - 7A
