I bought what the lady at Wally World called a tuberous begonia with the intention of planting them in a planter for my parents grave decoration for Memorial Day. I bought them because they were pretty without thinking about the care they needed. The lady said they would come back next year if I would winter them over in my basement. I guess my immediate concern is, will they tolerate a mostly sunny location for a week in the graveyard? I also bought them for my husband's parent's grave, but they have some shade during the day. Any suggestions on how I can make this work?

Also, what is the name of the old traditional begonias from 35 years ago?

Thanks in advance for any advice you folks can give me. . .
