We are not positive because we cannot see the leaves in detail, but the flowers resemble a species of Begonia.If it is a species of Begonia, it belongs to a large family of plants, native to many tropical and subtropical regions of the world. Outdoors, most grow best in pots in filtered shade, with sterile, rich, porous, fast-draining soil commercially available at your local garden center (not native soil from the garden), regular but light feeding with a slow release or organic fertilizer and enough water to keep soil moist but not soggy. Most thrive as indoor plants, in greenhouse, or under lath. Almost all require at least moderate humidity. Most can be propagated easily from leaf, stem, or rhizome cuttings if it is a Begonia, but we cannot be sure at this stage.
