I received my Planet Max a year ago and planted it in a smaller raised bed this past early October 2015. Perhaps it has gone into heat dormancy? It is very hot here currently and has been for about a month or more. I have numerous cultivars that did not bloom this year. I currently see scapes on about 7 or so plants (some seedlings and some named and registered daylilies). I guess daylilies do well some years and not so other years?
Now that I am thinking about it, in that particular bed, only 2 cultivars (out of 8) have bloomed. I also have Lady Neva, Fol de Rol, Get Jiggy, Winter Rainbow, Springfield Clan, Planet Max, and the two that did bloom - Webster's Pink Wonder and Beautiful Edgings. The leaves look ok. Only Lady Neva and Fol De Rol have produced substantial growth. The rest seem to have maintained their size from what they were a year ago. Maybe that raised bed has some issue? Or are some cultivars more picky when transplanted?
