GAgirl, Do you take your ginger indoors during the winter. I had one in Calif, it never bloomed in the 2 years I had it, but I loved the foilage so did not care about not blooming. If I could grow one here I would love it, but do not have a large enough house to be bring plants in for winter. Not esp if the ginger gets as big as the one I had.
No, they can stay in the ground here. They would probably bloom better if they were protected. I do have a shell ginger that I keep in my GH because i read somewhere that they would not bloom if they died back. Well this year they bloomed for me, so pretty.
marti001, why don't you let them die back with the first frost, cut off the foliage, and then bring in the tubers? Save a lot of space. Mine have been in the ground for years, die back every year and come back, but this is the white butterfly ginger and the pink "Elizabeth". I have one that looks like yours GAgirl, but I haven't put it in the ground yet. I keep my shell ginger in the greenhouse too, cause I'm in zone 8b.
