I bought this from Roots and Rhizomes several years ago, so I am not sure if the year of registration is correct on the AHS website, or if perhaps it was sold a while before it was registered.
Everyone who visits my garden asks for a piece of this. It really stands out, gorgeous color. Has rebloomed for me in zone 5. Winters well for me, but is a slower increaser for me.

Survived a Maine winter in the raised wooden beds then bloomed in late August and early Sept. Will be watching it closely. so far I like it.
