Hmm! I didn't realize they would come and go so quickly.
On weekdays, I only see them in the morning and late evening, and they get full morning shade. Maybe I should find my spotlights and light 'em up, then see what they do!

I am sure that some of the clumps have multiplied well, and maybe I should even divide them next year or the year after.
I'm not sure whether some of the older clumps have disappeared. In one area, I think I now have 6-8 big clumps, where there used to be 12-15 smaller clumps or singles.
