This is B. 'Mr. O'Flaherty' Brad Thompson named this begonia after me and when I first saw it I thought it is very unusual and looks hard to grow. Well, it is very easy to grow and one of my favorite begonias..

It really is an easy one to grow and does have great markings Mike! Brad did good with this one.
The one you sent is happily growing down at the botanical garden greenhouse.
How cool is that! I love it. And has those charming polka dots too on such a great leaf.
