What are the adaptations of hibiscus?

I'm thinking adaptation to pollination ...

1. red tubular flowers to attract birds

2. stamens fused into a tube around the style with its branched stigmas ... this keeps most of the pollen away from the stigmas and prevents self-pollination. Also, the position of the stamens and stigmas are just right for pollen transfer on the heads of visiting birds.
What are the adaptations of hibiscus?
I have seen hibiscus plants growing on an island in the Bahamas where it was just sand. A hurricane had come through several years previous to my visit and stripped the vegetation off the island. The hibiscus had reseeded itself or else the plants washed back.
