This summer has broken many records. I don't have to provide shade, but we've had many days in the 90's w/humidity to match. Ugh!!! Recently, I've been watering the raised beds once a week - overnight (I know, I know about overnight watering, but I can't do it easily when customers are around during the days)
I've recently moved a half dozen sorts of alpines in full bloom and they are doing OK because I watered the bejesus out of 'em from the start. I do that with daylilies all the time and as long as I don't divide the clumps, they don't even shock a little bit.
Usually we do have rain at useful, regular intervals - but not this summer. Lots of rain (and flooding) early and nothing like the usual in July.

This one is C. glomerata acaulis.
