I have noticed a correlation between vigor and ruffling and the energy  
resources of the plant. I had a cross a few years ago that showed this  
dramatically. There were only about 20 seedlings in the cross and only about  half 
produced increases by bloom time. The half that had increases were rather  
tailored when they bloomed. Those without increase produced well ruffled 
flowers  without exception. I have no doubt that the seedlings that had little 
ruffling  had the genes for ruffling, but not the vigor to make increase as 
well as  ruffling. Many of us see this in introductions from the various 
"iris paradises"  which are dramatically ruffled in their home gardens, but for 
us they bloom with  much more modest form. I again attribute this to genes 
for vigor under various  climate conditions. So we are often selecting for 
vigor when we think we are  only selecting for form.
