I have had this plant only since 2016 but it has been a great performer. It has bloomed both years, increased more than moderate, is sunfast, does not get blotchy. It reached 34", so should meet stats at maturity, the bloom's color is always consistent, that beautiful lavender grey which changes some as the day passes. Bud count was a decent 14 with 3 way branching blooming from July 27 to Aug 30. This is a stand out in the garden.
