Being that I garden in a cold climate area - and considering that my 'early' daylilies (ie, species) usally begin flowering in mid to later June and a 'few' registered daylilies will begin blooming either the very last few days of June or start in the first few days of July... I consider my midseason to be late July and first week or two of August.
Until recently (as I have added many more registered daylilies as well as seedlings), daylilies blooming into September were rare and only Moussaka bloomed into October.
So to judge 'season' ... when Explosion in the Paint Factory (listed in the database as a late season daylily) has its first buds showing the start of colour on the 20th of August... what would be the range of seasons for daylily blooms?
I suppose anything before July would likely be 'extra early', first half of July might be 'early' ... mid July to mid August is the majority of daylily blooms, so midseason (?). Anything around the end of August into September would be late season... and anything into October would just be crazy? Oops, I mean extra-late...?
Or is there some specific time frame for how long each bloom season 'should' last?
Any time after third week of August, we start hitting cold nights and could have frost at any point / any night... so from that point onwards, the daylilies blooming are definitely competing with cold weather ... yet still put out blooms for up to six or more weeks. Is that considered 'normal'?
Seedling of 'Sultry' continued blooming after the second week of September...
Wish I had not been so sick on return from Italy ... there were several daylilies still budded and blooming the second week of October, including Explosion in the Paint Factory, Moussaka, Fully Charged and Sharply Focused (and some of the seedlings). I just could not get outdoors to record and evaluate the bud & bloom counts or be sure how many other daylilies were also still producing buds.

And is there any particular designation for daylilies that will persist in blooming 'after' they are being hit by repeated frost...? If no, it seems like there should be.
