Thank you David. I checked Siloam Merle Kent and the bloom is really similar but it should be a lot shorter than mine, 18 inches, while this supposed NOID is 27. I searched in the database on here for height 27 and color mauve but nothing useful came up. Will wait the other blooms to see it better.
Forgot to say, it didn't went dormant the past winter. The only true dorman I have is Stella de Oro. The others all remained visibile through the winter.
