Will a potted hibiscus survive a North NJ winter if it's covered with plastic?

The hibiscus is a tropical plant, which will not survive a winter with snow and ice as is to be expected in North NJ. Bring the pot indoors when frost threatens. At a constant temperature of 60-70 deg. F the hibiscus will bloom indoors. At 40 deg. F it will retain its foliage. It likes regular fertilizing twice a month. Water frequently. Prune tops and, if needed, roots in fall when plant moves indoors. When danger of frost is gone return to partially shaded patio.

Only if the winter is covered with the plastic!
Reply:I have a beautiful potted Hybiscus and I live in Missouri. It comes in every winter because it would never survive the cold. I would never leave it out in a New Jersey winter.
