I love both of thse plants. Is Hibiscus Fireball and tropical cultivar? It is lovely. I have something called Luna Red that has lots of large red flowers like yours, but the plant is much smaller. It is hardy in our zone.

Your sunflower is perfect!! This year I have been doing a happy dance because I have sunflower(s). I have been trying to grow these for years and the squirrels always tear them down even before they bloom. But this year, mother nature placed a seed in a most unlikely place - the hollow of a large log - and there it grew, bloomed, and has since put out a few more small blooms. I will have to post pics. later.

Gorgeous sunflower & spectacular hibiscus. I WS lots of hibiscus colors and they're all covered with buds even this first year.
Great pictures--thanks for sharing!
