If you never deadhead them, they probably got overgrown and choked themselves out. I regularly and frequently deadhead mine. In late Fall, I leave the last blooms on for the finches when they show up looking for seeds.
Here in Iowa, our winters can get a bit chilly -- hanging at -15F for periods last winter. I cut the coneflowers to the ground in November. They were covered with snow for months, and they came back with a vengeance this year -- bigger, taller, thicker, and more populous.
Now, I have a lot of thinning to do. It's probably time for that, anyway, since they have been here a few years. Same thing with the daisies.
