Begonia "Happy Heart"

I guess this is a good example of the phenotypical begonia...love the almost star shaped leaves...I can understand how gardeners and plant lovers develop a preference for a certain type of plant...I love gesneriads..in the same way...I've never had the success with begonias that I've had with Saintpaulia, Achimenes, Streptocarpus or Episcia... and the plant Frankensteins are having a fine time with them too.
