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
