Elatior begonias (Begonia x hiemalis) are called winter-flowering begonias, because they require cool temperatures and short days to bloom. Nevertheless, growers can produce them year-round with the use of blackout curtains and temperature controls. As they decline after flowering, Rieger begonias, also known as elatior begonias, are often trashed. When given a dormant period, however, the old plant — or new cuttings taken from it — can be induced to flower the following winter, if not earlier.
Try to provide temperatures in the high 60s to 70 degrees Fahrenheit during the day and from 50 to 60 F at night. Water the Rieger begonia when the surface of the soil feels dry to the touch. Avoid splashing the leaves or watering in the evening when those leaves won't have time to dry.
Mature Height: 12-15 inches
