Yes, I have white ones with red centers. Mine are in the ground. Do you bring it in in the winter or does it stay out all year? If you leave it out all year I'd plant it in the ground.

Definitely hibiscus and if it's been it the pot for 5 years you need to either plant it or repot in a larger pot. If you do either you should get more blooms. It is probably very rootbound.
I agree with the others and by all means, plant it in your flowerbeds. Our Lord Baltimore hibiscus grew each year to at least 5 ft. tall and about the same in diameter. Bloomed in late July with large red flowers and it was so pretty. We decided to move it one year and when we dug it up, it weighted a lot! Cut it back to the ground in late fall and watch for bugs that eat holes in the leaves. First sign of holes, get spraying something on it.
