Yes, I was thinking rose of sharon, which is also a hibiscus, just not the tropical one.
There are double rose of sharon's as well:
and no, dusty boot, the new pictures didn't really help much. For ID we need to see the leaves, how the leaves are attached on the branches (alternate or opposite), the plant as a whole.
But from the glimpse we have of leaves and buds, I'm thinking some double hibiscus, either the rose of sharon, or the tropical.
