I found saving seed is easiest by removing the outer calyx and putting the pods in a dry warm spot to open.

If you look at the comments for Rosella in April 2008, there is one which answers your question in detail.

I have rossella growing and in the past have been successfull however the last two times i have tried to grow these they get to a height of say 400mm and they start a dieback with a white sap like liquid coming out of the bottom of the plant eventually killing it.Any help would be much appreciated we live up in the mountains west of Sarina yes we get frosts however the last rossella plants die back in late summer.
