I wonder if Thunbergia alata would do well in your area -- black-eyed susan vine. It's eye-catching, especially if no one else is growing it. I've seen the deep orange ones grown as perennial vines here, but in cold-winter areas it'd probably be grown as an annual and might work in hanging baskets. When I looked it up just now, I found it comes in lots of colors. Supposed to be easy from seed; haven't grown it myself.
