I think you are talking about Curcuma which is a ginger that has a natural dormancy in the dry season of the tropics. I grow these without problem here in PA since they can just be stored totally dry in their pots in my basement for the winter and then wake up when you water in the spring. In your zone they will just go dormant for the "winter". Best of luck finding them.....there are huge numbers of species/cultivars :o) Dan

Thanks Dan, Thats it, AJ
