there are probably 50 or more of these coming up in the flower bed from seedlings….not sure what they are. Thought they may be hibiscus, but leaves don’t look like any hibiscus that we have in that area.
you are correct – it is a hibiscus, and it looks like Hibiscus moscheutos or its hybrid. They die back to the ground in the winter.
