Begonias

Begonias form a highly varied genus of flowering plants grown for both colorful blooms and distinctive foliage. Depending on the species or hybrid group, they may be compact bedding plants, trailing basket plants, tuberous seasonal flowers, or leafy indoor specimens. ## Choosing a type The [Royal Botanic Garden Sydney’s Begonia guide](https://www.botanicgardens.org.au/our-science/our-collections/plant-families/begonias) describes distinct groups including rhizomatous, rex, cane, trailing, tuberous, and bedding begonias, with substantial differences in habit, foliage, flowering, and seasonal behavior. [Kew’s Plants of the World Online](https://powo.science.kew.org/taxon/urn:lsid:ipni.org:names:77126658-1/general-information) classifies the genus in the family Begoniaceae and describes it as a large tropical and subtropical genus. For this broad genus record, the live dimensions represent a compact example rather than a size limit for every begonia; other forms can be much larger or cascading. The current zone range likewise describes only a warm-climate subset, since some hardy species tolerate colder regions while many tropical types are frost tender. ## Light, soil, and water Light needs vary by group. Most cultivated begonias do well in bright filtered light or partial shade; some bedding types also tolerate more sun when acclimated. Use a loose, well-drained potting mix rich in organic matter and water thoroughly when the surface begins to dry, allowing excess water to drain. Keep plants away from prolonged soggy conditions. The [American Begonia Society’s general culture guide](https://www.begonias.org/basic-information/) emphasizes both drainage and the need to avoid drying or waterlogging the mix. ## Maintenance Remove spent or damaged growth as needed and pinch growing tips on plants that need shaping. Protect frost-tender selections from cold, and check the specific species or cultivar’s guidance before choosing a permanent outdoor site.
