We planted gayfeather this spring and were very happy with the flower, as it attracted a number of butterflys and hummingbirds. Is there anything that I need to do for the winter? We are in a heavy snow zone, and as it is, the flowers are nearly horizontal to the ground. Do they need to be "cut back" or not. Thanks for helping a rookie!

You can cut them back or let them die back naturally. They reseed like crazy, so if you don't want more you should cut them back. You could apply a loose layer of mulch for winter protection, but since you are in a heavy snow zone that probably isn't necessary...the snow acts as protection.
