Do hibiscus plants come back every year? Yes, cold hardy hibiscus plants will go dormant and come back in the spring every year in the right growing zone. Tropical varieties will stay evergreen in warm climates, but are otherwise grown as annuals in cooler climates. A perennial is one that grows year after year.
An annual, on the other hand, does not grow year-after-year. A plant that is an annual can be pruned back to a smaller size if it becomes too large. Annuals can also be cut back if they become too tall or if the soil is too dry.

How do I know if my hibiscus survive a freeze?
Below the lowermost cluster of the freeze-damaged leaves and above any swelling buds, put your fingernail into the bark of the stem. The green is live wood and the brown is dead wood. It will take a long time for the roots to recover if the stem is killed by a hard freeze.
If you find a dead stem, you will need to remove it from the tree. You can do this by cutting it off with a pair of scissors, or you can use a knife to cut it free. If you cut off the root, the plant will not be able to regrow it, so you should leave it alone until it regrows.
