Basically, they all did. It seems as if they were responding to a different triger. Such as a secondary vernalization preferntial signal. That is a certain amount of time as a mature plant. Or something similar.
Autumn Embers, a fall cylic SDB, blooms late in fall, normally around end of Sept. This year reblomed on Aug 10th. And not just one stalk, so not one of those occasional biological misfires. Never seen this before on this cultivar. It is my into and has been blooming here since 1989. Until this year has always rebloomed late Sept or early Oct. Or frozen out before rebloom. Never earlier, until this year.
As this is all a one time phenomenon for me, I have no idea what to make of it
But as I mentioned, very early bloom seson (about 2-3 weeks earlier then normal) and very warm summer with no extreme hot spells, and a good steady rainfall without any long droughts . An ideal and very rare summer weather.

Year to year (and region to region) weather/climate effects sure don't
make it easy to sort this stuff out! Pigments and patterns are easy in
Sounds like your "cycle" plants aren't daylength regulated. Might be
more like "summers" here. Which ones bloomed earlier than usual for you
