Kabby, I thought I had lost every single Shampoo Ginger after last winter. I finally got some tiny plants two months later than normal and every time one came up, I dug it up and potted it. I now have about 18 potted ginger and they are going to spend the winter months in a greenhouse. They will all go back outside in the spring. The White Butterfly Ginger doesn't seem to have a problem with mid to low teens (so far).
