Answer: I wouldn't take the plant indoors. Instead, winter it outside (it is quite hardy). Just to make sure the roots survive, insulate the pot by either wrapping insulation material around and under the pot or by setting the pot in a larger container and stuffing insulating material all around to keep the roots from freezing solid. You'll also want to protect the graft (swollen area) by wrapping insulation around it. The leaves will die and some of the newest stem tips, but the rest of the plant should be just fine. Once the leaves are gone and your plant has experienced some cold weather, move it close to the wall and under an overhang to protect it from harsh winds. Check the soil peridically during the winter months. If it is not frozen, you can water to help keep the roots hydrated.
Best wishes with your topiary - and with your new home!
