I went to our grocery outlet that is a warehouse with some things priced lower than in chain stores - the first thing I saw was a begonia, it stood out. It was B. 'Cathedral' It filled the cart. I brought it home and measured it - is just short of 3 feet across. It has lots of buds starting to open. The price was $15.99. Now I have to think of an excuse to go back and see what else might be there. That was the last place I would think of to find begonias.
