3.5 years later and I can say this:
In my 5b zone garden, it has prospered!! It is a late bloomer, starting at the end of July and this year went well into the very end of September/beginning of October.
This year, I had at least 15 scapes on my clump and it did a ton of bud building!
You can kind of see the scars from the spent blossoms with the bud building in progress.
