Answer: Rose-of-Sharon (Hibiscus syriacus) will grow in your gardening region, but tropical hibiscus - the kind with glossy leaves will not survive outdoor temperatures in your garden. So if you purchased tropical hibiscus, plan on enjoying them outdoors on your patio or deck this summer but taking them indoors in the fall when the temperatures drop. A hardiness zone is an indication of the lowest winter temperatures in your area. When choosing plants, choose those that are rated hardy to numbers from 1 to 7. This will ensure that the plants will survive your coldest winter temperatures. Tropical hibiscus is usually sold as an annual in your gardening zone, but if you take them indoors in the fall and back outdoors in the spring, you can grow them year around. Hope this clarifies things for you.
