Steve, I'm not sure about Prescott, but down here in the HOT desert, once you put out Bachelor Button seeds you have Bachelor Buttons for life. In my garden they come back every year. I try to control just how many come back by pulling a lot of them out before they set seed, and leaving a few here and there to seed at will. Seems to be working. There are true blue bachelor buttons too...so I love having them in my garden.
