question: Of the Saintpaulia and  Begonia flowering plants, which is better suited to growing indoors?
answer: African violet is a common household indoor plant
context: Title: Saintpaulia
  Passage: Saintpaulias, commonly known as African violets, are a genus of 6–20 species of herbaceous perennial flowering plants in the family Gesneriaceae, native to Tanzania and adjacent southeastern Kenya in eastern tropical Africa.  Typically the African violet is a common household indoor plant but can also be an outdoor plant.
  Title: Begoniaceae
  Passage: Begoniaceae is a family of flowering plants with two genera and about 1825 species occurring in the subtropics and tropics of both the New World and Old World.  All but one of the species are in the genus "Begonia".  The only other genus in the family, "Hillebrandia", is endemic to the Hawaiian Islands and has a single species.  Phylogenetic work supports "Hillebrandia" as the sister taxon to the rest of the family.  The genus "Symbegonia" was reduced to a section of "Begonia" in 2003, as molecular phylogenies had shown it to be derived from within that genus.  Members of the genus "Begonia" are well-known and popular houseplants.
  Title: Begonia
  Passage: Begonia is a genus of perennial flowering plants in the family Begoniaceae.  The genus contains 1,795 different plant species.  The Begonias are native to moist subtropical and tropical climates.  Some species are commonly grown indoors as ornamental houseplants in cooler climates.  In cooler climates some species are cultivated outside in summertime for their bright colourful flowers, which have sepals but no petals.
