Nice bloom there! B. boliviensis and its myriad hybrids are always a showy blooming plant for almost all summer. A bit difficult for me because of the heat in the Atlanta area (they start off well but often succumb mid to late summer - maybe their energy is used up by then with all the blooming?)

I consider the blooms of most begonias (excluding tuberous, Semperfloren types, and boliviensis types) as icing on the cake - as most begonias have showy leaves so while blooms are nice they are not the major attraction of the plant.

I got two at the time, the other one has different flower types, and are cream in colour

Gorgeous!
