I gave a number of plants and cuttings to my mom in the spring. Now she is sending me pics of all of them to ID again so she knows which ones should be brought in for the winter. I figured them all out but one, which has me completely stumped. It sort of looks like TX star hibiscus except I know for sure I didn't give her one of those. I can't find anything in my garden that looks like it. Anyone have any ideas?

Thanks, Kim
