Here in northern Italy, my specimens survive with temperatures - 6/8 C° they are either in full ground in a flowerbed with light protection by old tall pines, as in some pots where i grew from seeds I got some years ago. In my experience they don't form rich clumps and fear surface fungus which hurt their neck and then kill the tubers, expecially in warm wet springs. I never got seeds from my plants. a link to some lines written about P.
