Flowers are usually single but may be semi-double or double. Flowering occurs from late autumn to early spring. Stems are usually weak and require support. Pinch out the tips when the plant is young to promote bushier growth. The Elatior hybrids, which include the Reiger begonia, are similar to Lorraine begonias but they have larger flowers.
Elatior begonias are available in flower all year round.
Lorraine and Elatior begonias are usually discarded after flowering but can be restarted by cutting them back to within 3 inches of the crown. Reduce water and keep in a cool location. Increase water in spring . New shoots can be used as cuttings. There are also trailing types that are used in hanging baskets.
