    I love this plant. In zone 5 northern Il. it flowers from late May into early September. I pinch back in spring to promote dense branching or it will flop to the ground when it rains. Have had this plant 15+ years. No disease issues. Attacked once by rose slugs. No other pest issues. In my zone it does seem to need dividing every few years to maintain crown health. I like them best in the first two years anyway as they are smaller in size. Have often read that this plant is drought tolerant. It is not tolerant here anyway. Let some go dry in this year's drought too see how they would do. They stopped flowering, growing and died. All that received a little water from hose are fine. Pat
