I have had this cultivar in my garden since May 2014. The first bloom on it this year was April 24th, and it rebloomed at least two times this year. It still had blooms in mid September this year. The color seems to vary a lot in my garden, I like it best when it is the most purple looking.

I did not get the stats on it again this year, but I do remember thinking it was performing very well in the garden in 2017.
