Does anyone have B. Dorothy Behrens? I have lost this one in my collection. Also, with so many begonias changing names. Someone may have it but call it something else. Is there anyone with a true picture? It is a medium size leaf. I have seen it at least 4-6 inches across. It is a black, hairy leaf, and rhizo. type plant. If you like black leaf begonias it's beautiful. This is a good challenge if you can find it. I am willing to purchase it. Thank you.
