This plant used to be in the genus Eupatorium, but has been changed. I can see why, as it does differ quite a bit, but it is a nice blue for late summer.
Frilly, it is very hardy and trouble free. I have plenty to share, tree mail me if you'd like some this spring. It emerges late after weather has warmed, usually May here.
