Gerry, I am sure the plants will grow in the house over the fall/winter months, but that is just an educated guess. I brought a bunch of mine into one of the greenhouses last fall and they overwintered there. Of course they got bright light. I keep the temperature at or above 55 F in my greenhouses. I did reduce watering somewhat because they grew more slowly, but they did fine. These are outdoor plants though and to grow their "cones", they need to be outside in the spring/summer months.
