Neal, I agree, this is a great idea! Unfortunately too much of my landscape matures into a lot of mistakes. It's nice to see so many garden shot here. Even when I don't know exactly what I'm looking at the color, texture, size compositions translate well.
Polly, other than the phlox Neal mentioned, they wrap up here in mid-September, the Rose of Sharon bloom early July to late September, as do the Hydrangea. Last year Crocosmia emberglow bloomed early August to mid September and the Montauk daisy late September to early November. My favorite is Ajania pacifica. It starts blooming mid/late October and reaches peak around Thanksgiving. The flowers aren't much to look at but most welcome as a last reminder before winter sets in. Oh, and though mine are small the Russian sage are blooming in August well into September. I've read Gaillardia bloom/rebloom till late summer although as I killed mine last year I can't say for sure.
