Found this while on a walk. It was huge. Any idea on what it is?

Was it in a garden? If you want specifics, without seeing the rest of the plant, it could be H. laevis. There's also H. moscheutos. "Dinner-plate hibiscus." It's pretty hardy. There's a similar double form too (H. mutabilis) and lots of hybrids.
