Becky, that puckering on DDD05 is called "crepe". It's a texture feature. Some people love it, others hate it. For myself, I think it very much depends on the particular flower. The beautiful (and rust resistant) Stout Medal winner 'Brocaded Gown' has this feature.
(I went into the AHS Dictionary intending to post a link to their definition, but found that they do not have an entry for either "crepe" or "texture". Hmmm. )
Evaluating an iris seedling, hopefully for rebloom
