Begonias Do Not Like Full Sun and Intense Heat

It took most of the summer, but the Begonias finally decided to bloom.  They do not like intense heat and full sun blazing down on them all day.  While they arrived full of buds in the late spring, they never bloomed well. I think I saw one or two at a time throughout part of the summer, even when I shaded them.  I eventually moved them under a tree where they receive partial sun in the morning and dappled sun in the afternoon.  After a few days, the buds burst into lovely blooms.  I haven't decided whether I will plant these again in the spring.  I may try for a hardier variety that is a little more drought-tolerant.  Since our average first frost occurs from late October through early November, these have plenty of time to grow.

I'm thinking about meadowscaping my yard. That process will need to begin in the fall.
