I always have a number of daylilies rebloom, but not this year. It is very much weather related and somehow your South Seas didn't like the weather.

Have you been dry? We have had almost no rain for weeks and that has cut down on our rebloom.

It’s been a pretty mild summer and it’s typically pretty dry this time of year. I did give them slightly more water this summer than I normally do (which is zero supplemental watering). There was a good amount of frost damage in early spring and they’ve since had a nice reflush of healthy leaves. Maybe they spent their energy on that instead of more flowers? The Stellas right next to the SS are on their third round.
