Question: Of the Saintpaulia and  Begonia flowering plants, which is better suited to growing indoors?
Context: Pterostylis alata, commonly known as the striped greenhood, is a species of orchid endemic to Tasmania.  As with similar orchids, the flowering plants differ from those which are not flowering.  The non-flowering plants have a rosette of leaves but the flowering plants have a single flower with leaves on the flowering spike.  This greenhood has a white flower with prominent dark green stripes and a sharply pointed, brown-tipped dorsal sepal.  Similar greenhoods growing on the Australian mainland were formerly known as "Pterostylis alata" but are now given the name "Pterostylis striata". Austrobaileyales is an order of flowering plants, consisting of about 100 species of woody plants growing as trees, shrubs and lianas.  Perhaps the most familiar species is "Illicium verum", from which comes the spice star anise.  The order belongs to the group of basal angiosperms, the ANA grade, which diverged earlier from the remaining flowering plants, and, as such, it is the extant group after the Amborellales and Nymphaeales, that is sister to all remaining extant angiosperms outside of the ANA grade.  The order includes just three families of flowering plants, the Austrobaileyaceae, a monotypic family containing the sole genus, "Austrobaileya scandens", a woody liana, the Schisandraceae, a family of trees, shrubs, or lianas containing essential oils, and the Trimeniaceae, essential oil-bearing trees and lianas. 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. Parodia is a genus of flowering plants in the cactus family Cactaceae, native to the uplands of Argentina, Peru, Bolivia, Brazil, Colombia and Uruguay.  This genus has about 50 species, many of which have been transferred from "Eriocactus", "Notocactus" and "Wigginsia".  They range from small globose plants to 1 m tall columnar cacti.  All are deeply ribbed and spiny, with single flowers at or near the crown.  Some species produce offsets at the base.  They are popular in cultivation, but must be grown indoors where temperatures fall below 10 C . Studies that are in vivo (Latin for "within the living"; often not italicized in English) are those in which the effects of various biological entities are tested on whole, living organisms or cells, usually animals, including humans, and plants, as opposed to a tissue extract or dead organism.  This is not to be confused with experiments done "in vitro" ("within the glass"), i.e., in a laboratory environment using test tubes, petri dishes, etc.  Examples of investigations "in vivo" include: the pathogenesis of disease by comparing the effects of bacterial infection with the effects of purified bacterial toxins; the development of antibiotics, antiviral drugs, and new drugs generally; and new surgical procedures.  Consequently, animal testing and clinical trials are major elements of "in vivo" research.  "In vivo" testing is often employed over "in vitro" because it is better suited for observing the overall effects of an experiment on a living subject.  In drug discovery, for example, verification of efficacy "in vivo" is crucial, because "in vitro" assays can sometimes yield misleading results with drug candidate molecules that are irrelevant "in vivo" (e.g., because such molecules cannot reach their site of "in vivo" action, for example as a result of rapid catabolism in the liver). 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. 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. Lilium (members of which are true lilies) is a genus of herbaceous flowering plants growing from bulbs, all with large prominent flowers.  Lilies are a group of flowering plants which are important in culture and literature in much of the world.  Most species are native to the temperate northern hemisphere, though their range extends into the northern subtropics.  Many other plants have "lily" in their common name but are not related to true lilies. The indigenous people of the Everglades region arrived in the Florida peninsula of what is now the United States approximately 14,000 to 15,000 years ago, probably following large game.  The Paleo-Indians found an arid landscape that supported plants and animals adapted to prairie and xeric scrub conditions.  Large animals became extinct in Florida around 11,000 years ago.  Climate changes 6,500 years ago brought a wetter landscape.  The Paleo-Indians slowly adapted to the new conditions.  Archaeologists call the cultures that resulted from the adaptations Archaic peoples.  They were better suited for environmental changes than their ancestors, and created many tools with the resources they had.  Approximately 5,000 years ago, the climate shifted again to cause the regular flooding from Lake Okeechobee that gave rise to the Everglades ecosystems. The wildlife of Turkey is abundant and very varied.  Turkey is a large country with many geographic and climatic regions and a great diversity of plants and animals, each suited to its own particular habitat.  About 1500 species of vertebrates have been recorded in the country and around 19,000 species of invertebrate.  There are about 11,000 species of flowering plants; some of the world's staple crops were first cultivated in this area, and many of their wild relatives are still found here.  The country acts as a cross roads with links to Europe, Asia and the Near East, and many birds use the country as a staging post during migration.
