Is begonia elatior an annual or a perennial?

Answer 1

Elatior Hybrids (Reiger Begonia, Begonia x hiemalis, indoor begonia) are a cross between a fibrous (wax) begonia and a tuberous begonia. They have large flowers like a tuberous begonia and bloom continuously like a fibrous begonia. However, they are not as long lived as most tuberous begonias. When grown as outdoor plants in the summer, they are usually treated as annuals to be thrown away after 3 to 6 months. When grown as indoor houseplants, they can live several years by pruning back old stems to encourage new growth and flowers. You can also propagate Elatiors from leaf cuttings, but take care to bury at least one leaf node so the plant will grow a tuber that will sprout new stems.
