I think one of your begonias is B. 'Passing Storm' Not Passion
A friend of mine in Australia has the world check list with 16, 000 entries. I will check with him.
I had a begonia that I thought was Sblover for years. Found out it was named after Ziesenhenne's wifes family Selover. Ziesenhenne was the worlds most famous begonia man. Our Begonia group in Santa Barbara is named after him.
Did you buy your crassicaulis from GHW? The crassicaulis I got from them looked exactly like that but it isn't really crassicaulis. It is a heavy duty begonia. Now I just call it the monster or sprawler. Before it got frost bit two years ago it probably sprawled between 6 and 8 foot long.
Here it was 3 years ago (a year before the frost damage) on a hot deck in full sun. As long as it got watered every day, it laughed at its conditions.
flowerjunkie, I love your collection! So many unusual begonias out there, its a whole new world of discovery for me. I especially like the B.crassicaulis; love jurassic looking plants. Thanks for sharing!
Hey... how are you. I have lost all my begonias. Only one I have left is the Elk Horn. I'm propagating it like crazy to offer it in trade for ones I lost. I don't mind buying cuttings or trading for anything you might have extras of.
I just mustered up the nerve to clean out my green house these past few days with the help of my 16 year old Grandson and my Boy Friend. It was sad to see all those empty pots go to compost. I knew what lived in those and how much they were worth. :-(
