Daisy is correct to dig and store. I am zone 8 and do not have to dig. But I can tell you that here they are also grown in containers that are left out all year, cause I do not like to dig and lift. You could start with one or two grow them in containers. After first frost and foliage looks black cut off foliage leaving 2 inches of stem. With cold weather store the containers where they would not freeze, nor get wet. Bring back out in spring when cold weather is over. May you have a joyful week!
