Answer: Unfortunately the hibiscus, licorice vine, New Guinea impatiens, coleus and asparagus fern are all extremely sensitive to cold and need warm temperatures and bright light all winter. They would be considered houseplants or conservatory plants and will probably die if subjected to the cooler temperatures one would find in an unheated garage in mid winter. The rose, strawberry and loosestrife are winter hardy plants so should manage to survive in an unheated garage. Allow them to slow their growth as the season progresses and keep the soil just barely moist. The danger is that the roots or stems will rot if kept too moist, yet the plants should not dry out completely.
