I read that these were hardy to zone 6 and that they need a chilling period in the winter to survive. We have plenty of snow in the winter when it gets super cold that I could pack on top of it. And yes, I am thinking of putting it in the ground in a mini bog garden with sphagnum moss as the soil and some pebbles at the bottom for some drainage. I’ve always loved them but can not care for them indoors. Any thoughts?
