Most of the blooms should be normal in shape and size but there may be a few fused or otherwise misshaped blooms and maybe some polys. There are usually more flowers than there would otherwise be and they will be a bit crowded. In my experience they should go back to normal the following year unless the condition that caused them to fasciate in the first place repeats itself. There is a lot of discussion about what causes this but I don't believe that any specific cause has been identified. Some say Virus but ALL of my daylilies that have ever done this have come back in following years with normal scapes and green healthy looking foliage. None of my plants that have ever fasciated (daylilies, lilies, hosta, verbascum, alcea) ever died.
