Fortunately this plant has thrived this year. I’m not sure what I did different from past years, it’s put on quite a show all summer though. I read that the National Botanic Garden in Washington, DC has gardens specific to most states on display this summer and the begonia is in the Texas garden.
How pretty- plants seem to go in blooming cycles just like some insects are prevalent one year and not the next. Whatever the case you have one photogenic flower!
