National Flower?

On August 31, the Malaysians celebrate their national day. But they have already started to put flags and banners everywhere. I was surprised to see that many banners display the same type of flowers.

Obviously, these are Hibiscus (rosa sinensis). Malaysians have chosen the red five-petalled type as their national flower.

As a good Swiss, I can neigther sing nor cite the national anthem. We have one though, and a flag too. But a national flower? Not that I would know anything about it. Maybe, the Edelweiss (leontopodium alpinum) can be called nationa flower, but that's def'initely nothing official.
