They are perennials so come fall the frost will kill the top of the plants but the roots will be fine. Sometime after they have gone through a hard freeze where the temperatures drop below freezing for at least a few hours go ahead and cut them back to stubs or only three or four inches from the ground. If you want you can wait and do this early spring.
Come spring they are a little slow to get started so be patient. But once they start growing they really take off and by the end of July, early August they start making flowers.
