We remember the taste of Rosella jam from 30 years ago when we lived near Lismore, NSW. I picked up 2 plants from a market on the coast but am trying to grow them near Tamworth, frost country. At present they are still in pots on the verandah & surviving with a few beautiful, red "flowers". I want to seed save from them. Any hints would be very welcome.

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.
