Mine are both about 12 feet tall now and each have about 6 pups growing around the parent plant. They both still look great outside now (I used freeze pruf). I am going to try the leave cage method that worked on my basjoos last winter and see if it works. I think it will help that they are both against the foundation of my house. the soil does not freeze within a couple feet of the foundation of my house. I know this because I have some canna lillys against my house and they come back every year and I only cover them with about 6 in of mulch. I have some pictures of the bordelens in my gallery.
