Does anyone on here grow butterfly ginger in a cooler climate? I have had a plant for several years now that never produces flowers. It grows outdoors in summer in a very sunny location. It is currently growing in a 14" container which it has completely filled. It's probably about 6 feet tall or a bit more. Very healthy, very lush. I leave it outdoors late enough to get a light frost which kills the foliage back a bit. After that I cut it back and it winters down the basement. I also use Jack's blossom booster on a regular basis during the summer. Any suggestions would be greatly appreciated.
