I read on one site that the Hardy Hibiscus Hybrids have as many as 5 different wild species crossed to get the variability we have now. I don't recall what the other 3 were.

Hibiscus moscheutos, H. coccineus, H. laevis, H. grandiflorus, and H. dasycalyx. They are classified as Hibiscus section Meuchhusia and are all North American natives. I wrote this article on them for NGA a few years ago.
