Mike,
Lovely collection of colour and so much variety.
Don't have much of what you show, here in bloom yet, except Shastra daisies.
Have found red hot poker quite short lived here. The cultivars never got to the size of needing division.
I really get Loretta's comment, being surprised myself, that you still have columbines in bloom.
Agree with Scott: maybe actually a maiden pink. Maiden pinks have proven very long-lived here.
