Hi Dick, glad you found your way to this site.A bit more chatter here than on the other two sites.
Della, I share your enthusiasm for flowering immaculatum!! So many new tangents to follow now.
About 10 years ago, I knew of two people in Australia that had this species.The fellow, now deceased, who brought it here received his seed from the RHS and grew an impressive amount of species on his 30 acre block in the back hills of the Dandenongs.He was a bit of a bushie and didn't like visitors, but would chat for hours on the phone.He sent me pollen of Japonicum and other stuff when I was in Tassie.Unfortunately he died shortly after I relocated back to the mainland and I think his collection was lost.
