I live in south central Illinois. I have been told that it is possible to plant hibiscus in the ground; but for the first winter, they should be covered with plastic (such as a trash bag) and then to place a garbage can over the plant. Is this a possible means to keep hibiscus alive in the winter here?

It might be possible, but it could be difficult with tropical hibiscus. If you get many freezing nights, even with the extra protection, they would have trouble surviving. Tropical hibiscus, if it survived, would need the extra protection every year. They may have been talking about hardy hibiscus as well, and that needs no extra winter protection where you live.
