I grow American Freedom. Had one plant that bloomed year before last and it was next to a similar pant and the tags got blown away so I got another one last spring and when it bloomed I could see it was still there and doing great when I compared it to the one I just got. I now have a clump in 2 spots in case one bites the dust. Do get it as it is a beauty and a good grower here for sure. I am zone 3-4.
