Thanks everyone for suggestions. I will consider all.
It used to be my rose of sharons, and butterfly bushes and phlox could be depended on to reliably bloom in September. Now they're blooming around the first part of August at the latest. So very odd. My hydrangea paniculatas are getting buds on them now. Always used to be end of July.
Anemone is a great idea. Most of them were not reliably hardy for me, but now they might be, and they would bloom later. Crocosmia also is a great idea, and I'm going to try some other varieties other than Lucifer. Thanks Evan.
This is my first year with brugs, Neal. A kind DGer sent me 8 starts, really nice ones. I haven't killed them yet.
