Received this from David's Dragon Fly farm back in June 2015. I have few notes except to say that it has been divided a couple of times and sold in local plant sales.
It does make dark purple blooms, hard to show in photos, and is most times darker than the photos show it to be.
It does make proliferations:
It makes a nice root system.
The color varies from a dark purple red look to a dark purple.
