Can Hibiscus Recover from Freezing Temperatures?

Recovery depends on the type of hibiscus and your climate. Tropical hibiscus (Hibiscus rosa-sinensis) is hardy only in Zones 9–11. If winter temperatures dropped below about 20°F, the plant is likely dead. However, wait until spring to see if new shoots emerge from the base. Once warm weather arrives, prune back to healthy growth.

Hardy hibiscus (H. moscheutos) is root-hardy in Zones 4–9. Plants die back completely and can be cut to within a couple of inches of the ground in late fall or early spring. New shoots will emerge from the crown in late spring after the weather warms.
