I think it may depend on whether you are referring to the tropical type of hibiscus or the perennial type more often referred to as
rose mallow. The perennial type will die back to the ground each winter leaving just sticks and will send up new shoots in
spring, sometimes late
spring depending on warmth. The tropical kind usually will not survive below 32 degrees F, but might overwinter during a mild winter. The stems would probably be dead and it would send up new growth from the ground. If you don't know which one you have, just wait to see what happens in the coming weeks...and hope it comes back! :-)
