Not wrong about bougainvilleas being tough. Not even a nuclear blast would shift them. The nurseries here are pushing a variety they call "Bambino" which is small and flowers prolifically. You might find that sort of plant available in SA rather than locally.

Another which grows well on the coast is Crinum pedunculatum. I've seen it growing wild on beaches with a lot of salt spray and occasional waves breaking on them in rough weather. Another is Debdrobium discolor, a beautiful orchid growing along beaches, even in sand and coral gravels, and hit with a lot of salt spray.

Also take a look around the Tropical Plants forum here on DG:

You might be able to get some hints from there as well.
