I live in the suburbs outside of St. Louis, zone 6-a on the map. We have had cannas planted for over 15 years. They are planted along the side of our house and get the sun all day. We have never split them or brought them in for the winter. We do not cut them back either. They come back healthy and hearty every year. They also continue to spread out.
