I grow it here every year. Were borderline zone 7/8, our winter lows down to 15 or so once or twice with an average for mid to low twenties. Small plants will die, larger plants will die back, but re sprout in the spring if I leave them. Which grow fast enough in our hot summers to give a crop again in the fall. Usually I harvest the whole thing for eating and overwinter divisions in a unheated greenhouse or shelterhouse. Only because I'm going to dig it up for harvesting it, and if I put back unrooted divisions back they won't survive.
The ultimate goal of farming is not the growing of crops, but the cultivation and perfection of human beings. - Masanobu Fukuoka
