|According to your zip code, you are in USDA zone 7. The average coldest winter temperature in zone 7 is between 0? F and 10? F. so Rose-of-Sharon (Hibiscus syriacus) is winter hardy in your zone. Tropical hibiscus (Hibiscus rosa-sinensis) is not hardy and will need to spend the winter months indoors. Hope this clarifies things for you.
