I live in southeastern Wisconsin, Zone 5. Can I bring the plant in and utilize a grow lamp to keep my plant through the winter and ready for next summer?

Yes! They are quite easy to keep inside, as long as you do not overwater them. Let the top 1/3 of the soil dry out between each watering, and make sure to fertilize, at half strength, with an all purpose. Do so once before bringing it in, and once before putting it out for the year.

Prune it as often as it needs, indoors, since it will need it near constantly. Repot if it outgrows its container.

If you decide to do so without artificial lighting, then you will not feed it, and let it go semi-dormant. It will not grow much, and will only require watering when almost completely dry, only. It will lose most leaves this way, though.
