The Q&A Archives: Winter Hardiness

Question: I purchased a Fullmoon Hibiscus to plant near my other hibiscus which is winter hardy. Now I see that it is only tolerant to 30 - 40 degrees. Is there anyway this could be left outdoors in winter? I am in zone 4.

Answer: Unfortunately, I don't think so. The tropical hibiscus (Hobiscus rosa sinensis) just can't tolerate cold. It does however make a good houseplant during the winter months, so you might consider bringing it inside to a very sunny window. Keep the soil evenly moist but not soggy and avoid both warm and cold drafts. With luck, it will bloom for you during the winter.
