I am zone 5 and have a huge bulb I bought at the Flower Lawn and Garden Show, the gentleman selling them swore they were our zone, I knew better but I bought it anyway. This time of year I put it in our solar room and it will bloom later this winter. I can never get it to bloom in the summer. It is HUGE in a huge pot. I just keep it cause it is unique. Like a lot of folks it might not be worth the real estate it takes up. But while I have room to spare I will keep it.
