Alessandro,
It grows naturally a couple of hours from here at the coast. It also grows in the rainforest verge at the Botanic Gardens here in Canberra. I've posted some pics of it in the Australian Native Plants at the ANBG" topic. I love it. I do have a small plant of it, but I really have to be careful with it as it doesn't like much frost. They can get rather large at maturity, with some of them down the coast flowering at around 2m tall or more.
