Horntoad, you say you love Hibiscus and are trying to enlarge your collection.
I didn't see you list Heartleaf Hibiscus;

This one is not winter hardy in North Central Texas, but it should be hardy for your area.
You didn't list, Neches River Rosemallow, this one should work well for you

I can send you seeds of both if you like.
