I have not had any of my rebloomers re-bloom ... yet. We have had a wetter and slightly cooler summer than most years so maybe a few of the dwarfs will give it a try. Immortality has grown a lot this summer too, so maybe it will try for a fall bloom as well.
And Arlyn - sorry to hear you have litter box issues! You must have nice garden soil... (no pun intended?).
