Rose-of-Sharon prefers full sun and appreciates protection from winter winds. Flowers are formed on current season’s wood so pruning, if desired, should be done either in late fall, in winter after leaves drop or in early spring before buds form. Note: if the trunk survives your WI winters and leafs out, there would be no need to prune. Tropical hibiscus (a.k.a. hibiscus rosa-sinensis) is frost tender is most of the U.S. and should be brought inside. Hardy hibiscus (a.k.a. hibiscus moscheutos) is typically winter hardy to z5.
