Meet the Hibiscus, a genus of flowering plants in the mallow family, Malvaceae. According to Wikipedia, the plant favors the sub-tropics and tropics, making it quite at home in southwestern Florida. The picture is a focus stack composed of five separate macro images.
The pistil and stamens (vertical, center) are quite prounced and colorful in their own right. I had to refresh my botany knowledge to recall that the pistil is the top-most sticky tip. The stamens (beneath the pistil) actually consist of two parts: a stalk called a filament, topped by an anther where the pollen is produced. This will be on the exam. ;-)
