This is a pretty cold hardy species, which dies back to the roots in autumn. If you planted it outside and live in USDA zone 6 or warmer you shouldn't have to do anything, just leave it alone and wait. If you plant in a pot you'll want to put it in your garage or basement where it will be protected from temperature extremes. Don't water it during winter; wait until it warms up and sends out new shoots.
