Mine have been great. Flowered all summer.
Matt, they will die down now, will blacken. It's nature's way of winding down.
Now, for me, because they are new to me too, I'm going to keep some in the ground but dig up the rest and pot up the rest and keep them in the GH. I will do that very soon now.
I will cut down the foliage, slightly trim any long roots and pop into 3 litre pots...bigger if needs be. I will water them and keep them outside for week or so or longer whilst it's still nice and mild. When it gets colder I'll take them indoors.
