I have not had the same experience with my yellow flags (Iris pseudacorus or my blue flags (Iris versicolor). They were in the same situation: water rose to above their crowns (growing points) during the spring, and rot set in quickly. If I had not lifted them they would undoubtedly have died, even though they did have "water roots". The difference seems to be whether or not they have developed "water crowns". The water level rose to about 2" above their emerged stalks. They had been in normal soil, then flooded in the spring, and the water kept rising. Maybe something wrong with the water? It comes from a natural underground stream that only runs in winter/spring with a limestone channel. The pH of this water is about 8.2, as compared with the surrounding soil of 8.8 > >Just some ideas. +More > >Cheers. > >Paul Tyerman >Canberra, Australia.
