What is the name of this large, WHITE cane begonia
Ok, I have become obsessed with finding this very large, white cane begonia. I first saw it on an Australian garden blog (see link below). I have been unable to find it in the U.S. I have tried Begonia Society websites, begonia specialty nurseries and eBay - all with no luck. Asking the blogger for a cutting is impractical because he is in Sydney, Australia.
I would really like to know the name of it - more than the name 'Begonia coccinea', which is also used to refer to many pink varieties.
Note that this begonia has no white spots on the leaves.
Do you know the name of this begonia? And even better, do you know anyone who has a cutting they would swap for the pink variety, which I have?
