A rose of sharon bush is nice. Mine blooms from around July 4 into the middle of autumn.
Petunias will bloom that long, but only if you pluck the dead ones off before they can grow a seed packet. Also, gladioloas are pretty good for that, but if you want to save them, you have to dig up the bulb each fall if you get snow. Also, marigolds, bachelors buttons, sweet williams, and pansies are good.
