Woohoo! Blooms in September! Way to go, Digger!
Me, too, but I didn't take pictures except of this one because it just started blooming four days ago.
It's an Olallie seedling called Mia (VT). or M.I.A. (VT) kind of hard to tell on their all-cap website.
It's pretty enough to be Mia, but it's late enough every year that you might think it's M.I.A. before you see scapes.
