I read somewhere there are two rosewoods. One is a wood from South America. Its got some rosiness to it, but its a bit more camphoraceous.

The other one is actually made from steam distilling branches of rose plants. I haven't smelled that (and I can't seem to actually find it) but its suppose to be rose like with a strong green planty smell. Like how petitgrain is like neroli, only greener.

I did do a mixture recently using the first rosewood and some rose absolute to see if it would work well as a way to make the rose stretch. It was okay, but I think geranium would have done a better job. Also, it was for a bath salt (christmas present for the my mother) so I think it all works out.
