Peak season here is mid May
Our daylilies start blooming end of March and early April depending on the weather. We will have blooms (rebloom) until November it looks like. We would have more, but after we are done hybridizing we try and keep the scapes cut off so the energy will go into growing not blooming. I've never really tracked the seasons of what we have to see if they bloom according to their registered season, but I do know that in 2011 nothing was blooming according to their bloom time. I had Mids blooming before EE and E blooming before EE, lates blooming in mid season. Sometimes I think they will just bloom when they get good and ready. They may need to get acclimated to the zone they are in before they bloom true season, but then again if they are say a late in a Florida hybridizer's garden then they may just be an E or EE in a more northern garden.
This year I only have 3 lates and they were blooming with the EM and I had a M that wanted to send up a scape late; it bloomed mid May last year.
