I have approximately 50 iris plants, mostly bearded, chosen for the variety with hardly any two alike, all planted 3 years ago. I still have about a dozen not blooming and am playing with depth, etc. Of the remaining 3 dozen blooming, one full dozen have apparently reverted to a base strain and I now have a dozen mostly white with purple striping plants, another 7 are now DEEP purple, and 5 medium yellow. What happened? I suspect I can't change them back but need to know what happened to prevent it when I replant.
