With a bit of care, you can collect thousands of hibiscus pictures from the Internet. The various societies and nurseries list many and the Yahoo Groups mail lists allow you to interact and share flower images.
I list here alphabetic thumbnail and slideshow albums of mostly plants available in Australia. They are plants I grow or have grown and even some I'd like to grow soon. I have used some pictures submitted by others on the Net until I have a better one of my own. I also use some to show the variable appearance of a bloom in different conditions.
