Very pretty! It'll be more than a month before any of mine bloom but love seeing your pictures! We have snow again today and it's supposed to continue into tomorrow. Heard on the radio on our way back from the airport that there was already 19" somewhere up along the northern border of CO, thank you God that we're not supposed to get that much!
You are about right with our timing. My tree peonies bloomed around June 24, but don't have any ready to produce blooms yet. Then it jumped to a couple of weeks later for the next. This year may be an exception due to the constant sun and warmth.
